  • Description:China general plug valve manufacturer,factory and supplier for reduced bore and full bore design.
China general plug valve manufacturer,factory and supplier for reduced bore general valve,plug valve with different material and pressure class.The action of two sealing vanes of reduced bore general valve,plug valve mounted on the cock is the key to the working principle of the double block and bleed valve.The two separate sealing vanes of reduced bore general valve,plug valve are compressed on upper and lower ends of the valve bore(double block], and when the reduced bore general valve,plug valve is closed, the bleed valve will be opened to check the sealing effect(bleed].

Reduced Bore General valve,Plug valve feature:

1. In the reduced bore general valve,plug valve's opening/closing process, there is no contact between the sealing surfaces of the valve body and the vane, so the sealing surfaces suffer neither friction nor wear, contributing to the general twin seal plug valve's long service life and small opening/ closing torque;

2. For the reduced bore general valve,plug valve's maintenance, there is no need to remove the valve from the pipeline but just remove its bottom cover to replace the vane pair, thus very easy for the maintenance;

3. The reduced bore general valve,plug valve's cavity is plated with hard chrome and the sealing area is hard and smooth;

4. The elastic seal on the vane is made of the fluorine rubber and molded and formed in a groove of the vane surface.The fireproof metal-to-metal seal is used as the backing of the elastic seal;

5. The reduced bore general valve,plug valve is provided with an automatic bleed device(optional) which can prevent the abnormal pressure rise of the valve cavity and check the valve's effect after the valve is completely closed;

6. The reduced bore general valve,plug valve's opening/closing indicator is in sync with the opening/closing position and can accurately display the valve's opening/closing status.
