The Uni-Flow Double Door Check Valve is a compact wafer design and is a popular choice when space is a major factor in valve selection and pipeline design. The compact design features a non-slam spring-assisted closing and is suitable for water, wastewater, oil, weak acids alkaline liquids, etc. Tight closure is obtained by utilising a soft seat in either EPDM or NBR.
Available in sizes 50mm – 600mm
Cast Iron body with either 304 stainless steel or ductile iron chrome plated disc.
Thin Wafer Check Valves are compact and extremely lightweight and suitable for mounting between a wide range of flanges. Available in steel or 316 stainless steel the Thin Wafer Check has a Viton or EPDM seat for leak proof sealing.

Uni-Flo Ball Check Valves are compact and mainly used to protect wastewater pumping stations. Mainly used on water, sewage water, and viscous fluids, the ball check valve consists of a rubber-encapsulated ball to backseal any reverse flow.
Silent closing, no water hammer
Good sealing
Full bore flow, large flow
Small resistance
Loss or water head is 50% lower than swing check valves
Installation: horizontal or vertical
More Info. (.pdf)
The Uni-Flo wafer swing check valve is an economical alternative to the traditional flanged swing check valve. The lightweight wafer-type valve consists of a 304 stainless steel disc, and on reverse flow will have a positive shutoff owing to the resilient seat.
Low Head Loss
Pressure rating – 16 Bar
Available in sizes 50mm – 600mm
Uni-Flo Swing Check Valves are especially suited for the prevention of reverse flow. Designed to BS5153, the valve allows for full flow and can be installed in the horizontal or vertical position.
