1、 Overview of Electric High Temperature Ball Valve Products
The GQ941PPL/H electric high-temperature ball valve from Shanghai Yuhu Company uses a new sealing material as the valve seat, which increases the service life by 3-5 times compared to similar products with PTFE sealing. Electric high-temperature ball valves have the advantages of 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 the electric high-temperature ball valve adopts the corresponding national standards, expanding the scope of use of ball valves. High temperature electric ball valves are widely used in industries such as petroleum, chemical, rubber, papermaking, and pharmaceuticals, and can replace globe valves, plunger valves, and quick discharge valves. Applicable media: acidic media such as water, steam, and thermal oil. Structural characteristics of electric high-temperature ball valve: The ball and sealing ring of the high-temperature electric 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.
