Main feature:The valve is opened/closed by the valve disc moving in a direction parallel to the valve seat hole axis and can only be installed on horizontal pipelines with the major function of preventing medium backflow when shutting down the pump and maintaining the water column required by pumping.
Wafer Type Dual Plate Swing Check Valve
The valve body passageway is designed in a wing-shaped streamline type, allowing the medium to flow through the passageway rapidly and steadily with no noise. It is opened or closed by the valve clack moving to-and-fro through the valve body guiding axle under the spring effect. It can be installed on horizontal and vertical pipelines.
