Pneumatic diaphragm regulating valve

Product Overview

Pneumatic diaphragm regulating valveModel ZMAT/ZMBT, valve body cast iron/steel lining F46/stainless steel lining PFA, valve sealing diaphragm EPDM+PTFE, specification size DN20-200, rated pressure PN10, product structure sealing is simple, only the diaphragm needs to be sealed without other packing sealing. The product advantages are simple and reliable sealing, good adjustability, and can be used for regulating viscous/corrosive media with poor fluidity. The sealing diaphragm is easy to replace and the sealing element can be replaced on site

Note: Solid particles/high temperature/high pressure media cannot be used

Execution mechanism: Multi spring thin film actuator

Connection method: flange

Flange standard: JB/T94 HG20592

Gas source pressure: 300kPa
