Product Description:
H71H/W wafer lift check valve This valve is composed of valve body, valve disc, spring, etc. It is installed horizontally or vertically in the pipeline system to prevent the medium from flowing backwards. It has short structure, small volume and light weight. The flap is closed quickly, the water hammer pressure is small; the flow passage is smooth, the fluid resistance is small; the action is sensitive, and the sealing performance is good.
