The stroking times for the multi-spring A100/A200 Series diaphragm actuator depend on the application.
The factors which influence this characteristic are the stroke, air supply pressure, size of pipework connection,
spring rate, operation action (air to open, air to close) and type of the possible associated positioner.
Actuator stroking time of less than one second can be obtained by using boosters.
Economical design.
Simply top and top side mounted hand-wheels.
Height strength actuators case with rugged design.
Low volume between diaphragm and actuator case.
High stability.
Low hysteresis.
Compact design with reduced height.
