  • Flange high temperature valve

Short Description:

The integrated high temperature ball valve designed by our company adopts new sealing material as the valve seat, and is sealed with the same kind of product polytetrafluoroethylene. Its service life is increased by 3-5 times. It has the advantages of stable performance, reliable sealing, small friction force, light switch, high temperature resistance, wear resistance, oil resistance, corrosion resistance and long service life. The high temperature ball valve is consistent with the stop valve, plunger valve and blowdown valve in structure and length, which expands the application scope of ball valve. It is widely used in petroleum, chemical, rubber, papermaking, pharmaceutical and other industries, and can replace the stop valve, plunger valve and fast blowdown valve Valve. Applicable medium: water, steam, heat transfer oil and other acids, service temperature: ¡ÃƒÂœ 350 ¡æ.
