QJ41M high temperature ball valve/QJ641M pneumatic high temperature ball valve/QJ941M electric high temperature ball valve are ball valves that use new sealing materials as valve seats and are sealed with similar products such as polytetrafluoroethylene, which increases their service life by 3-5 times. High temperature ball valves have the advantages of stable performance, reliable sealing, low friction, lightweight switch, high temperature resistance, wear resistance, oil resistance, corrosion resistance, and long service life. The structural length of high-temperature ball valves is consistent with globe valves, plunger valves, and drain valves, expanding the range of ball valve applications. They are widely used in industries such as petroleum, chemical, rubber, papermaking, and pharmaceuticals, and can replace globe valves, plunger valves, and quick drain valves. Applicable media: acids such as water, steam, and thermal oil, operating temperature: ≤ 350 ℃.
The ball and sealing ring in the high-temperature ball valve adopt special processing technology and sealing materials, which make the surface roughness and roundness of the ball meet the standard requirements, thereby improving the sealing performance, service life, and high temperature resistance. The clockwise movement of the handle drives the valve stem to rotate the ball, allowing the medium to pass smoothly.
