Check valve:

The check valve is also called a one-way valve, its role is preventing the backflow medium pipeline.Open-close part by medium flow and power to open or closed, to prevent the backflow medium valve check valve.

Check valve is according to structure, can be divided into the lift check valve, swing check valve and butterfly valve.

Effect of check valve:
Check valve installed in the piping system, whose main role is to prevent the media back, is a medium pressure valve to open and close the automatic valve.

Feature of angle valve:
1, the valve motion sensitive, good sealing performance
2, check valve short trip, close impact small
3, check the horizontal or vertical pipe pipe can be used, easy to install
4, valve flow smooth, fluid resistance
5, check the overall structure is simple and compact, attractive appearance
6, the short length of the check valve structure
7, small size, light weight
8, valve closed fast, small water hammer pressure
9, long life and reliable performance

Common faults:
①The disc break
②Medium flow back.

Media back reasons:
① sealing surface damage;
② sandwiched impurities. Repairing and cleaning the sealing surface impurities, can prevent backflow.
