D100RA Multi Spring Pneumatic Diaphragm

D100RA Pneumatic Diaphragm ACTUATORS Pneumatic diaphragm actuator of this series adopts multi-spring structure with compact, high performance and big thrust. The working principles areas follows: electricity or gas signal from controller will enter the diaphragm room after converted into air pressure by positioner to form push force to act on the diagram and make the push rod move. Meanwhile the spring is compressed until the acting force is balanced with counter-acting force to make the push rod reach preset position.  Specifications Type Rotary Shaft Motion Type D122RA D127RA D135RA D14LRA D15LRA Type 220 270 350 450 550 Nominal Diaphragm Area (cm2) 188.82 314.33 555.88 956.83 1,548.82 Air Supply /Spring Range (KPa) 400/120~280 Max.
