AV-MH-KA (Metal Air Valves)

Combination Air Release & Air and Vacuum Valves

AV Series

AV-MH-KA General

AV-MH-KA

Combination Air Release & Air and Vacuum Valves First Operation: Venting air from a filling pipeline The standard valve allows discharge of trapped air while the system is being filled with liquid. The valve will remain open, even at very high air flow velocity (A), until the liquid has reached the float and lifted it to its closed position (B).

Available for valve models with suffix “K” and “KA”.

Second Operation: Vacuum Breaking (Air Intake) of a draining pipeline Decrease or the pressure in the system to negative value and the simultaneous drainage of the valve chamber, forces the floats down, allowing the admittance of air into the pipe, thus preventing negative pressure and possible collapse of the pipe (C).

Available for valve models with suffix “K” and “KA”.

Third Operation: Release of dissolved air from a pressurized pipeline Air that is being released from the liquid in the pressurized system or being introduced into the system from open sources and pumping vortexes, accumulates in the air release valves located at high places.

The accumulated air forces the liquid out of the valve chamber, so the floating force of the bottom float decreases.

The bottom float then drops, allowing for the trapped air to be vented through the small nozzle at the center of the top float. Then the liquid level rises, the bottom float is lifted and the nozzle closes (D).

Available for valve models with suffix “KA” only.

AV-MH-KA-SA General

AV-MH-KA-SA

Surge Arresting Device (SA) for AV-MH-KA Valves Features • Surge Arresting – Automatically prevents water hammer pressure surges associated with air release valves operation.

• Optimum performance – Air outlet can be adjusted according to surge analysis results, on site to a required aero-dynamic performance. The SA addition is assembled on user selected valves only (at local high elevated points). The flow through other valves remains unrestricted.

• Simplicity – Can be easily assembled on any of AV-MH series air valves.

• Reliability – Simple, durable mechanism, fabricated from high grade materials. Can be serviced without having to put the air valve out of service.

Function When air is admitted into the pipe, an in “Air Pocket” is created in the local high points where the Air / Vacuum valve is located.

The returning flow re-fills the “pocket”.

Too-high velocity of the approaching water column may generate a pressure surge when it reaches the valve.

Operation of the SA addition Air venting The Surge Arrestor addition to AV-MH Series valves limits the air outflow, when the escaping air velocity exceeds a threshold value.

This optional addition creates a temporary, slow closing “Air Cushion” that decelerates the water velocity, preventing water hammer effect.

Adjustment of the air outflow can be done by plugging or un-plugging a set of bores in the SA adjustment plate (see pictures right side).

Vacuum Breaking (Air Intake) Decrease or the pressure in the system to negative value and the simultaneous drainage of the valve chamber, forces the floats down, allowing the admittance of air into the pipe. The SA disc is in its low position, allowing unrestricted air flow into the system.
