Compressed Air Single-acting Linear Actuator Rotary Cylinder
Diaphragm Rubber Rolling Pump Valve Rubber Diaphragm
Rolling Pump Valve Rubber Diaphragm Product Overviews:
Compared with the rubber corrugated diaphragm used in regulating
valves, the rolling diaphragm has a higher pressure resistance.
Almost all the pressure load of the rolling diaphragm is supported
by the piston, and only a small part of the liquid pressure or gas
pressure is supported by the narrow area of the diaphragm, so the
rolling diaphragm can obtain greater pressure bearing capacity and
higher thrust.
The rubber diaphragm is mainly used in the pneumatic film actuator,
which can convert the control signal (DC4～20mA or 1-5V) output by
the controller into the linear displacement of the valve stem
through the (intelligent) electric valve positioner and the
pneumatic film actuator. Or valve shaft angular displacement
accessories.
