The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

Functionality

The Star 595 Pressure Control Servovalve is a two stage, four way design that provides a differential pressure output in response to a low power electrical input signal. The 595 has been designed provide a far greater level of proportional pressure control of a load across the C1 and C2 control ports independant of required flow rate. Conventional flow control sero valves have extremely high pressure gain and therefore not best suited to many force control systems. The 595 has been designed with a dynamic response bandwith suitable for most servo control applications but can also be modified to specific system parameters.

First Stage (Torque Motor) The flapper is rigidly fixed perpendicular to the armature (soft iron). These components are supported and pivot on the flexure tube, the tube also acts as a seal between the electromagnetic first stage and the hydraulics of the second stage. Permanent magnets fix a magnetic field through the pole pieces towards the ends of the armature. The air gaps between the armature and pole pieces are set equally so that the flapper is in the vertical position. The armature is positioned inside two coils (one either side)

Second Stage (Bushing & Spool) The bushing (sleeve) has a number of fixed ports which vary in area and frequency depending on the operational design and flow requirements, these are shown as ‘P’ and ‘R’. A spool outside diameter is match ground to the bushing bore and spool lands are also precision ground to the bushing ports to provide a knife edge condition whilst opening and closing the ports. The bushing has additional galleries which provide spool drive force and proportional feedback.

First & Second Stages The torque motor flapper is mechanically positioned between a pair of matched nozzles (jets). The nozzles are fed by a matched pair of inlet orifices which drop the main supply pressure to approximately half. With no input signal to the coils there is zero pressure differential across these nozzles and therefore the spool is held at null.

When input current is applied the armature becomes polarised and moves in accordance to the level of current flowing. This movement is translated to the flapper which now causes a differential across the nozzles and in turn forces the spool away from null. At the same instance the control port pressures rise one side and fall the other, these pressures are monitored at the ends of the spool so that the output pressures can be controlled extremely accurately. The pressure curve is factory set based on nominal operating pressure set back at the pump.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.

The flow tolerance for standard servovalves is ±10% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

Function The Star series 902HF is a 3-stage, high flow servo valve for use in 3-way or 4-way applications within a closed loop control system of position, pressure (force) or velocity.

Typical applications include:- HAGC rolling mill - Resonant testing of turbine blades - Friction welding - Seismic exploration - Tensile / compressive testing - Aircraft landing gear testing - High rate tests - Dynamic ride simulators The design consists of a 4-way, 2-stage pilot nozzle-flapper spool servo valve (pilot) providing high fidelity control to a main stage spool with a large cross-sectional area. The pilot can be supplied with a variety of flow rates, build materials and band-widths offering high performance and stability whatever the application demands, other pilot stage designs are also available.

The main stage has manifold interface for clean access to all ports including the pilot stage and is supplied as standard (6 port) where the pilot supply (X) and pilot return (Y) can be set at higher or lower levels to that of the main stage. The design can also be configured to accept traditional side entry pipe fittings such as SAE O-ring or BSPP thread forms.

Installation When mounting the valve with the control ports positioned vertically the spool will tend to creep downwards when the main supply pressure is turned off. Care must be taken during startup to avoid bump due to instantaneous correction of the inner loop feedback signal.

Never command the pilot stage servo when < 4 bar exists at the main stage P to R ports. Essential lubrication will be lost and could lead to severe damge to the spool and sleeve assembly.

Fluid cleanliness In closed loop systems that require high degrees of resolution i.e. force or pressure control it is essential to equal or better the recommended ISO cleanliness levels. Off-line filtration has been proven to effectively remove particulates across the main ISO classification levels without detriment to fluid composition. There is also a very significant reduction on the dependency of inline filters that can and do fatigue when high transient pressures exist.

Additional condition monitoring can provide warnings on a number of elements during service and effective flushing procedures. Please feel free to contact our sales team for further details.

The flow tolerance for standard servovalves is ±20% of the rated flow at 100% rated input signal.

Typical Load Pressure Difference v Input Signal

Rated Signal [In] is the specified input voltage or current of either polarity to produce rated flow. Rated input does not include null bias values.

100 80

Rated flow corresponds to the flow at rated input at 10 bar or 70 bar, with no load, therefore in 4-way valves there will be a pressure drop of 5 bar or 35 bar respectively across each land.

60 40 % Supply pressure

70 Valve pressure drop ∆p (bar)

20

Load pressure difference versus input signal indicates typical differential pressure gain between ports C1 (A) and C2 (B) for standard lap spools. Negative and positive overlap change this characteristic signifcantly.

0 -20 -40

Internal leakage comprises of tare first stage and laminar leakage between spool and sleeve. With critical lap conditions in 4-way designs the leakage peaks through the null region.
