Main Steam Gate Valve

Product Size: NPS 2-24, DN50~600
Pressure rating: CL600~2500, PN100~420
Design standards: ASME B16.34, NB/T 47044, JB/T 3595

Stable and reliable sealing performance, excellent performance, and long service life.
The sealing surface of the gate and valve seat is welded with cobalt based hard alloy, which is wear-resistant, high-temperature resistant, corrosion-resistant, scratch resistant, and has a long service life.
The valve cavity adopts a pressure self tightening seal. Under the action of medium pressure, the valve cover moves upwards, forming a seal at the conical sealing ring. The higher the medium pressure, the greater the sealing force, and the reliable sealing.
The valve stem has undergone tempering and surface nitriding treatment, resulting in good corrosion resistance and friction resistance. It has an inverted sealing structure to ensure that the valve does not leak out of the valve stem during operation, and the valve stem packing can be replaced.
