Pneumatic Handwheel High Temperature Ball Valve QJ641M/F
1. Pneumatic with manual high-temperature ball valveOverview:
Our company's overall high-temperature ball valve design uses a new type of sealing material as the valve seat, which is sealed with similar products such as polytetrafluoroethylene. The service life of the ball valve has been increased by 3-5 times. The "TOMOESH" brand high-temperature ball valve has the advantages of stable performance, reliable sealing, low friction, lightweight switch, high temperature resistance, wear resistance, oil resistance, corrosion resistance, and long service life. Its structural length matches that of globe valves, plunger valves, and drain valves, expanding the range of ball valve applications. It is 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 ℃

5.Pneumatic with manual high-temperature ball valveStructural characteristics and working principle:
|
|
The ball and sealing ring in this type of 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.
