Cast steel globe valve

Product overview:

The stop valve only allows the medium to flow in one direction and is suitable for use in cutting or throttling situations. It has various structural forms such as straight-through type and right-angle type stop valve. It is widely used in water, oil, gas, steam and other media conditions.

Structural features:

1. The product has reasonable structure, good sealing performance, and high safety and reliability.

2. The sealing surface is welded with Co-based carbide, which has good wear resistance, corrosion resistance, scratch resistance and long service life.

3. The valve stem has been modulated and surface oxidized to have good corrosion resistance and scratch resistance.

4. When the nominal pressure is greater than 25MPa (CL1500), the middle cavity adopts a self-tightening sealing structure. The sealing performance increases with the increase of pressure to ensure the sealing performance.

5. The valve is equipped with an inverted sealing structure, which ensures high safety and reliability.

6. The material of the parts and the size of the flange and butt welding end can be selected according to the actual working conditions or user requirements to meet various working conditions.
