Wafer Type Swing Check valves is usually installed in pipeline system, prevent medium from flowing back, check valve is automatic valve that it is opened and closed by pressure of fluid. In the past, we use H74 flange coupling swing type check valves & H71 flange coupling lift type check valve.
Series - 150 To 600
Traditional check valve’s volume is big, strong resistance of fluid, Water-hammer’s pressure is high when valves close, repair and installation is inconvenient, service life is not long.
