- Structural features of imported electric gate valves
:<
r
-<
- &;
The valve adopts pressure self-tightening seal or valve body and valve cover gasket sealing structure, which is safe and reliable to use. <
r
-<
- &;
The valve disc adopts a double gate plate with a universal top structure in the middle, which can automatically adjust the fit between the valve disc and the valve seat sealing surface to ensure the valve's Sealing<
-.
This structure is easy to maintain, saves costs, and has good interchangeability of valve discs. <
r
-<
- &;
The sealing surface of the valve disc and valve seat is made of cobalt-chromium-tungsten carbide by plasma spray welding. The sealing surface has high hardness and is friction-resistant. Resistant to scratches and has a long service life. <
r
-<
- &;
The valve stem is made of nitrided steel and has a surface nitrided treatment for high hardness, scratch resistance, corrosion resistance and long service life. <
r
-<
- &;
The electric device is equipped with a torque control mechanism, an on-site operating mechanism and a manual and electric switching mechanism. <
