Pneumatic high temperature ball valve Q641M

Short Description:

The whole high temperature ball valve designed by our company uses new sealing material as seat and PTFE as sealing ball valve. Its service life is increased by 3-5 times. 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
