Product Usage
H71H, H71W type PN10~PN40 clamp lift check valve consists of valve body, valve disc, spring, etc., installed horizontally or vertically in the pipeline system to prevent backflow of the medium.
Features
1, with a short structure, small size, light weight
2, the valve flap is closed quickly, the water hammer pressure is small
3, the flow path is smooth, the fluid resistance is small; the action is sensitive, the sealing performance is good
