Twin Seal O bit Plug Valve

Applications
The double seal rail valve is applicable as an ideal device for cuttingoff media in pipelines of aviation kerosene, crude oil, light oil,naturalgases, liquefied petroleum gases, pipeline coal gases,chemicalmedia, etc.

Characteristics
1.In the 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 valve'slong service life and small opening/closing torque;
2.For the 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 valve's body and plug are full-bore so that the medium can
flow through the valve without any flow resistance, and it's alsopossible to clean the pipeline to overcome the shortcomings of the reduced bore valve;
4. The valve's cavity is plated with hard chrome and the sealing area is hard and smooth;
5.The elastic seal on the vane is made of the fluorine rubber and molded and for medina groove of the vane surface.The fireproofmetal-to-meta seal is used as the backing of the elastic seal;
6.The valve is provided with an automatic bleed device(optional)which can prevent the abnormal pressure rise of the valve cavityand check the valve's effect after the valve is completely closed;
7.The valve's opening/closing indicator is insync with the opening/closing position and can accurately display the valve's opening/closing status.
