H76X/H(DDCV Series)valves are mainly composed of body, disc(valve stem), spring and etc. The short closing stroke of disc and function of spring may strengthen closing effect and reduce the sound of water hammer and stamming. H46X/H are flange connection butterfly check valve. These two types of valves are mainly used in water supply system. high-rises and industrial zones. Thanks to their shorter structural length compared with ordinary check valves, they are especially applicable for space-restricted locations.
