Forged steel globe valve

Short Description:

The working principle of forged steel globe valve is to make the valve unblocked or blocked by rotating the valve stem. Usually full bore globe valve, 90 degree angle switch, light, small volume, can be made into large diameter, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often closed, not easy to be eroded by medium, widely used in various industries. Classification of forged steel globe valve: low pressure forged steel ball valve, high pressure forged steel globe  valve.

The structural advantages of forged steel globe valve are as follows:
1. The forged steel stop valve adopts the pressure self tightening seal, and the two ends of the branch pipe of the valve body are welded.
2. The sealing surface of forged steel cut-off Shu valve seat and disc is made of cobalt based cemented carbide plasma spray welding, with high wear resistance and scratch resistance.
3. The valve rod has good corrosion resistance and scratch resistance after anti-corrosion nitriding treatment
