Product Description

Flexible Iron Body DN100 Class 150 Stem Spring EPDM Seat Silent Wafer Style Check Valve

Product Description

The dual plate check valve is an all-purpose non return valve.

It is much stronger, lighter in weight and smaller in size.

Working employs two spring-loaded plates hinged on a central hinge pin.

When the flow decreases, the plates close by torsion spring action without requiring reverse flow.

This design offers the twin advantages of No Water Hammer and Non-Slam simultaneously.

FlowValve Dual Disc Check Valves are available in Wafer Type, Lug Type, Flanged Type.
