Product Description

Double Disc Check Valve Retainerless Wafer type HR76

Wafer end swing check valve is mainly composed of three parts: body,  disc( stem),  spring. The short closing stroke of disc and the spring force improve the closing effect,  while also reduce the pressure surge  and  slamming noise.

PRODUCT DETAILS
