Electric High-Temperature Ball Valve

Product Model: QJ941M
Product Application

QJ941M Electric High-Temperature Ball Valve
The valve body is of an integrated high-temperature type, using new sealing material for the valve seat. Compared to ball valves using PTFE as the seal, its service life is increased by 3-5 times. It features stable performance, reliable sealing, low friction, easy switching, high temperature resistance, wear resistance, oil resistance, corrosion resistance, and long service life. The high-temperature ball valve has the same structural length as globe valves, plunger valves, and blowdown valves, expanding its application range. It is widely used in petroleum, chemical, rubber, papermaking, pharmaceutical, and other industries, and can replace globe valves, plunger valves, and quick blowdown valves. Applicable media: water, steam, thermal oil, and other acids. Operating temperature: ≤350°C.
