American standard stop valve-Globe valve series-截止阀厂家-上海冠环阀门制造有限公司

Product structure characteristics

The American standard globe valve only allows one-way flow of medium, suitable for use in cutting or throttling situations. The opening and closing parts are cylindrical valve discs, with a flat or conical sealing surface. The valve disc moves in a straight line along the centerline of the fluid. Widely used in medium conditions such as water, oil, gas, and steam.

Main structural features
1, product design and manufacture according to ASME B16.34 and BS 1873 standards, reasonable structure, reliable sealing, excellent performance, beautiful appearance.
2, sealing surface surfacing Co based cemented carbide, wear resistance, corrosion resistance, abrasion resistance, long service life.
3, the valve stem after tempering and surface nitriding treatment, has good corrosion resistance and abrasion resistance.
4, the pressure ≥Class1500 cavity adopts a self-tightening sealing structure, the tightness increases with the internal pressure, to ensure the reliability of the seal.
5, the valve is equipped with reverse sealing structure, sealing reliable.
6, the material of the parts and the size of the flange butt welding end can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.
