BALL CHECK VALVE - BC SERIES

APPLICATION & CHARACTERISTICS

These full port ball checks with uninterrupted flow (equal to bore of pipe) are resistant to clogging and are ideal for wastewater, stormwater treatment, pumping dirty fluids. There is no accumulation of debris/deposits and the valve can be cleaned in-line without removal of entire valve and other neutral liquid applications. They can be used in horizontal & vertical service. BC series check valves have a low head loss and are self-cleaning due to the rotating ball.

VALVE

The swing check valves with rubber covered disc belong to the last generation of swing check valves, developed in order to improve the performance and the technical characteristics. These valves are manufactured in ductile iron, with the swing in ductile iron fully covered with NBR rubber. These swing check valves allow the full passage of the flow, with no water losses (compared to classical swing check valves with disc in cast iron). The disc doesn’t need any maintenance & avoids any noise during closure. Epoxy coated inside & outside, these swing check valves are suitable for potable water.

Face to face length EN 558-1 serie 48, DIN 3202 F6. Flanges BSEN 1092-2 and AS 4087/AS 4331.1 PN10 - 16 (PN25 also available to 350NB)

Optional Accessories

Proximity Switch, Backflow Actuator, Oil Dash-pot, Air Release Plug on the Cover.

OVERVIEW

The unique design of the hi-strength fabric reinforced rubber flapper disc creates an elastic spring to close-against the flow, combined with the tilted body seat (closing angle 35o) act to reduce the closing time, minimise the water hammer and flow reversal. Simplicity of design with three components (body, disc & cover) in one valve, and disc, hinge and pin are integral and fully encapsulated with special rubber for maintenance free, longlife, 1,000,000 continuous cycles tested with no sign of wear or distortion to the valve side and seat, body and cover are ductile iron. This valve will operate trouble free for a longer period compared to conventional check valves.

OVERVIEW

Valves are manufactured and tested in accordance with EN 12334 PN 10/16/25, TIS 383 PN 6/10/16/25. MSS-SP 71 class 125/250, and also meet the requirements of AWWA C508. The tilting disc check valve accomplishes full flow opening by having the disc pivot or tilt in the flow media. The opening stroke range in much less than that of the conventional swing check valve, therefore reduces opening and closing time critical to controlling flow reversal and reduces water hammer. The full flow area with lower headloss ensures Uniflo tilting disc check valve wil operate with the highest efficiency and durability.

FEATURES

Sizes are available from DN 80 mm - DN 1800 mm. (3”-72”)

Optional accessories Signal switch, By-pass, Hydraulic cylinder (top/bottom/side mounted)

1. Pivot Pins and Bushings Maximum strength is achieved by using large diameter high tensile pins.

2. Grease Fittings

Lubrication is not essential however optional grease fittings are used to assure even longer life.

3. Disc Position Indicator Indicates Disc Position.

8. Inspection Ports Ports allow access to the upstream and downstream sides of the seat, and also serve as mounting ports for optional dashpots.

4. Disc and Seat Rings

Superior wear and gall resistance are achieved through the use of materials having a high Brinnell Hardness (BHN) together with a selected difference in hardness between the disc and seat rings.

Leak tight seating is attained at all working pressures by utilizing a 20° seating angle which provides excellent sealing characteristics. This angle is self releasing and therefore prevents any binding of the disc and seat.

7. Stop Lugs

Positive stops are accurately positioned to prevent disc flutter at both high and low flow velocities, while maintaining ultra low head loss characteristics.

5. Disc

A hydrodynamically balanced design ensures minimum resistance to flow, lift and stabilisation, and good flow characteristics.

6. Body

Ultra low head loss is the result of streamlined body contouring and a flow area through the seat which is a minimum of 40% greater than nominal pipe size.

ASG SERIES (IRON)

NON-SLAM

SUPER-CHECK is a non-slam check valve because it operates on flow cessation, not flow reversal. The normal position of the plates is closed, held against the seat by the unique spring design. As flow begins, the heels of the two plates are lifted off the seat face on the central rib.

This cracking pressure is less than 14 kPa (2 psi) across most of the range (larger sizes can be more). As flow increases, the plates then pivot against the spring pressure. Since the heels have already lifted off the seat there is no scrub or wear, either on the seat, body or plate seating surfaces. A pressure of only 28 kPa (4 psi) is required to keep the plates fully open (up to 400 NB).

When flow stops and the pressure ceases, the spring closes the plates. Flow reversal is then stopped by the closed Supercheck valve and in fact any back pressure only serves to make the valve seal more tightly.
