Air Pneumatic Actuator Cylinder Valve Rubber Diaphragm Introduction:
In the design of some medium and low pressure regulators, in order
to solve the problem of unbalanced pressure regulating valve disc
and improve the performance of the pressure regulator, the method
of installing a balance diaphragm is often used. When a balancing
diaphragm is installed, the differential pressure between the inlet
pressure and the outlet pressure of the regulator can be increased.
In the regulator industry, it is called a balance diaphragm in
terms of use, and it is called a rolling diaphragm in the rubber,
instrument, machinery and other industries.
The rolling diaphragm is in the shape of a top hat in the free
state. It is made of rubber with silk cloth. The top middle hole is
used to install the valve stem. In order to install, fix and seal,
the top and bottom can have O-ring edges. Or in the form of fixing
holes around the bottom edge.

Air Pneumatic Actuator Cylinder Valve Rubber Diaphragm Material details:
For the present, common materials for rolling diaphragm are: natural rubber (NR), nitrile butadiene rubber (NBR), the performance of the two materials can meet the needs of most industrial environments. In special industrial environments (high temperature resistance, acid and alkali resistance) could use EPDM, fluorine rubber (FKM), neoprene rubber (CR) for production, but the cost is relatively high.
