The Pneumatic Diaphragm Rotary actuator share the working system of the diaphragm linear actuator in the diaphragm part.
Subsequently, a piston-crank mechanism converts the linear motion of the stem to another rotary, which can perfomance
in quart turn valves such as butterfly valves, ball valves or plug valves.
A handwheel can be incorporated for manual actuation.
Pneumatic Diaphragm Rotary Actuator can be used for regulating and ON/OFF services.
