Standards&Features:
The structural characteristics of the clamp check valve.
1.The structure length is short, its structure length is only the traditional flange check valve 1/4~1/8.
2.Small size, light weight, its weight is only the traditional flange check valve 1/4~1/20.
3.The valve flap closed fast, water hammer pressure is small.
4. Horizontal pipe or vertical pipe can be used, convenient installation.
5. The flow channel is unobstructed, the fluid resistance is small.
6. Sensitive action, good sealing performance.
7. Short stroke, close the impact force is small.
8. The overall structure is simple and compact, beautiful appearance.
9. Long service life, reliable performance.
