Due to the small friction between the sealing surfaces during the opening and closing process, the cast steel globe valves are relatively durable, the opening height is not large, the maintenance is convenient.
Features of cast steel globe valve:
1. The structure of the cast steel globe valve is reasonable and the seal is reliable;
2. the sealing surface is welded with hard alloy, which has good wear resistance, corrosion resistance, anti-friction performance and long service life;
3. Stem quenching and surface nitriding treatment, good corrosion resistance and anti-friction performance.
