What are the benefits of a double-sealed general's sealing surface?

(1) There is no contact between the sealing surface of the valve body and the sealing surface of the sliding plate during the opening and closing of the valve. Therefore, no friction and wear on the sealing surface, long service life of the valve, small switching torque:

(2) When repairing the valve, there is no need to remove the valve from the pipeline, just open the valve bottom cover, replace with a pair of sliding plates, maintenance is very convenient:

(3) The valve body and cock diameter is reduced to reduce the cost:

(4) The valve cavity is plated with hard chrome, and the sealing area is hard and smooth:

(5) The elastic seal on the sliding plate is made of fluorine rubber and formed into a groove on the surface of the sliding plate. Metal-to-metal seals with fire protection are used as foil for elastic seals:

(VI) The valve has an automatic decompression device (optional). After the valve is completely closed, the pressure in the valve chamber can be prevented from increasing abnormally, and the effect of the valve can be tested:

(7) The valve switch indicator is synchronized with the switch position and can accurately display the valve switch status.
