It has the advantages of stable performance, reliable sealing, low friction, light switch, high temperature resistance, abrasion resistance, oil resistance, corrosion resistance, long service life, etc. High temperature ball valves are in line with globe valves, plunger valves and sewage valves, and their structure lengths are in line. The ball valves have been widely used in petroleum, chemical, rubber, papermaking and pharmaceutical industries. It can replace globe valve, plunger valve and fast sewage valve. Applicable medium: water, steam, heat conducting oil and other acids, using temperature:<350 ~C
The sphere and sealing ring in the valve adopt special processing technology and the latest sealing material, which make the surface roughness and roundness of the sphere meet the standard requirements, thus improving the sealing performance, service life and high temperature resistance.The timing plate handle drives the valve stem to drive the ball to rotate, so that the medium can pass smoothly.
