This check valve protects the pump by bypassing the discharge pressure that instantaneously rises when the pump starts. It also absorbs shock by linearly opening the water hammer cushion valve to prevent a water hammer resulting from a surge in pressure
by the backward flow of water inside a standing pipeline when the pump stops. In addition, this product has a port soft sealing structure, thereby ensuring perfect air tightness at normal times.
