How to judge the quality of a check valve

2023/12/28

1、 Sealing performance:

Check valves should have good sealing performance to prevent medium backflow. The sealing performance can be determined by observing whether there is water leakage after the valve is closed.

2、 Circulation capacity:

A good check valve should have a large flow capacity, which can minimize flow resistance and pressure loss as much as possible. The flow capacity can be determined by measuring the pressure drop when flowing through the valve.

3、 Corrosion resistance:

A good check valve should have good corrosion resistance and be able to operate stably in various media for a long time. You can refer to the corrosion resistance of valve materials to determine.

4、 Service life:

A good check valve should have a long service life and be able to maintain good working performance. The service life can be determined by referring to the durability of valve materials and the reliability of structural design.

5、 Convenience of operation:

A good check valve should have the characteristic of being easy to operate and be able to easily close or open the valve. The convenience of operation can be judged by operating the valve.
