Check Valve Series
Description:
This valve can also be called clack valve, non-return valve or one-way valve. This type of valve can open and close automatically on the force from the flow of medium. It is a kind of automatic valve.
Application:
According to the material of check valve, this clack valve can be applied to the various pipeline systems. When the pressure might surpass the setting on the main system, this kind of clack valve can also be available. The main function of this check valve is to prevent the backflow of medium, the reverse of pump and its driving and the leakage of the medium in the containers.
Features:
The load of this check valve often changes. And the frequency of open and close is small. Once this non-return valve is closed or opened, it can work for very long time and does not require the moving parts to work. In most actual working condition this check valve is often closed rapidly. This fast closure may destroy the other parts and the whole pipeline system. In order to avoid this trouble, new structures and new materials are adopted in the design of check valve in our company. This can ensure the applicable performance of our one-way valve. At the same time, the impact of the trouble can also be minimized.
