Features of American standard cast steel globe valve
1. The products are designed and manufactured according to ASME B16.34 and BS standards, with reasonable structure, reliable sealing, excellent performance and beautiful appearance;
2. The sealing surface overlaid with Co based cemented carbide has good wear resistance, corrosion resistance, abrasion resistance and long service life;
3. The valve stem has good corrosion resistance and scratch resistance after quenching and tempering and surface nitriding treatment;
4. The cavity with pressure ¡Ý class1500 adopts self tightening sealing structure, and the sealing performance increases with the increase of internal pressure, which ensures the reliability of sealing;
5. The valve is equipped with reverse sealing structure, which is reliable;
6. The material of the parts and the size of the butt welding end of the flange can be reasonably selected according to the actual working conditions or user's requirements to meet various engineering needs.
