Membrane operated pressure control valve

摘要

The pressure control valve, with a membrane control action, has an elastic thermoplastic control membrane (6) without a center opening. It has no passage connection with the membrane plate (18) at the pressure side or the membrane plate (21) at the low pressure side, to lie loosely between them. The control membrane can carry laminated part membranes of a different plastics material, on the front or rear surfaces.
