H71 ANSI Wafer lift check valve(long series)
H71H(W) Check valve consists of valve body, disc, spring, etc. It is installed horizontally or vertically in the pipeline system to prevent media backflow. It has short structure, small volume and light weight.Fast disc closing, low water hammer pressure;The flow passage is unobstructed and the fluid resistance is small;Sensitive action, good sealing performance.
Clip lifting type check valve is to rely on the flow of the medium itself and automatically open, close the disc, to prevent the medium backflow valve, also known as the check valve, one-way valve, reverse flow valve, and back pressure valve.Check valve belongs to a kind of automatic valve, its main function is to prevent the backflow of media, prevent the reversal of pump and drive motor, as well as the release of container media.Check valves can also be used in piping where pressure may rise above system pressure to supply an auxiliary system.Check valves can be divided into swing check valves (rotating according to the center of gravity) and lifting check valves (moving along the axis).This class of valves should generally be installed horizontally in the pipeline.
