QJ41M High Temperature Ball Valve

QJ41M high-temperature ball valve/QJ641M pneumatic high-temperature ball valve/QJ941M electric high-temperature ball valve is a ball valve that uses a new sealing material as the valve seat and is sealed with similar products such as polytetrafluoroethylene. Its service life has been increased by 3-5 times. High temperature ball valves have advantages such as stable performance, reliable sealing, low friction, lightweight opening and closing, high temperature resistance, wear resistance, oil resistance, corrosion resistance, and long service life. The structural length of high-temperature ball valves is consistent with that of globe valves, plunger valves, and drain valves, expanding the scope of ball valve use. They are widely used in industries such as petroleum, chemical, rubber, papermaking, and pharmaceuticals, and can replace globe valves, plunger valves, and fast drain valves. Applicable media: water, steam, heat transfer oil and other acids, operating temperature: ≤ 350 ℃. The ball and sealing ring in the 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 timing plate moves the handle to drive the valve stem to rotate the ball, allowing the medium to pass smoothly.

2 piece ball valve flange end

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a "floating ball") to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.[1] The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status
