Weir type diaphragm valves are lined with plastic, rubber lining, the lining enamel and unlined structure is the most widely used in various types of diaphragm valves in a form of the throttle characteristic, can be used to vacuum. Corrosion resistance and good anti-particle medium. Reliable sealing, and low cost. The body overall structure of the casting and forging welding, forge welding the structure of the valve body material more dense, can be used in high vacuum mining Connect the end of the form: flange, threaded, butt welding and socket welding, etc. Drive mode: manual, electric, pneumatic Nominal diameter range: DN15 ~ 400mmGB/T12239-1989 MSS-SP-88- 1988 ISO5752-1988 BS5156-1985
