QP41M-16 High temperature ball valveDetailed product description：

The QP41M-16 high-temperature ball valve uses a new type of sealing material as the valve seat and is sealed with similar products such as polytetrafluoroethylene, which increases the 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 ℃

Structural characteristics and working principle:
The ball and sealing ring in QP41M-16 high-temperature ball valve adopt special processing technology and the latest 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.
