POPU Valve: WCB Swing Check Valve
H44H cast steel swing check valve is suitable for large diameter occasions with low flow rate and infrequent flow changes, but it is not suitable for pulsating flow, and its sealing performance is not as good as that of lifting type.
The purpose of the swing check valve is to prevent the hydraulic impact when the medium stops flowing or backflows.
