Product Introduction
Introduction:
There are two common types of full-cover rubber check valves: wafer type and flange type. H77X, H77J fully encapsulated rubber check valve is composed of valve body, valve disc, valve stem and spring and other components, which are connected by clamps. Water hammer is significantly reduced due to the short closing stroke of the disc and spring loaded. Because its structural length is shorter than that of general check valves, it is more suitable for places with limited installation space.
Application:
Suitable for water supply and drainage network of cities, industries and high-rise buildings.
