Basic information:
Simple, simple, and sound, and the lining, medium flange bolts, and the valve, the lifting valve, and the vertical valve. The brackets and the valve cover the shape of the gear operation, the standard flange connection
The sealing cover is not easy to wear and bruised, the sealing is good, the valve valve and the body cover of the valve are not relatively sliding, so wear and bruises are not heavy, the seal is good, the service life is long.
The fluid resistance is large, because the internal medium channel of the body is more torsional, the fluid resistance is large, the power consumption is large.
In the direction of the flow direction, the pressure PNG 16mpa is generally used in the downstream flow, the medium is flowing under the valve below the valve, and the pressure PNG is 20mpa, which is generally used against the current, and the medium flows down from the top of the disc. When used, the cut-off valve medium can only flow to the flow and cannot change the direction of the flow.
