Pneumatic High Pressure Globe Valve Product Features
1. Meticulous material selection, compliant with domestic and international standards, rational structure, and aesthetically pleasing design.
2. The disc and seat sealing surfaces are overlaid with iron-based alloy or Stellite cobalt-based hard alloy, offering excellent wear resistance, high temperature resistance, corrosion resistance, and anti-galling properties, ensuring a long service life.
3. The valve stem undergoes quenching and tempering as well as surface nitriding treatment, providing good corrosion resistance and anti-galling performance.
4. Compatible with various piping flange standards and flange sealing face types, meeting diverse engineering needs and user requirements.
5. A comprehensive range of valve body materials; packing and gaskets can be reasonably selected based on actual working conditions or user requirements, suitable for various pressures, temperatures, and media conditions.
6. The back seal employs a threaded connection seal seat or is overlaid with austenitic stainless steel on the body, ensuring reliable sealing. Packing replacement can be performed without shutting down the system, offering convenience and speed without affecting system operation.
