Operation Description
The air, or supply fluid, pressurizes the cylinder chamber relevant to the operation to carry
out (opening or closing).
This pressure starts the linear motion of the piston and the consequent rotation motion of
the rack and pinion mechanism, to which the valve stem is coupled, in required direction.
For local or remote operations related to the actuator, please refer to technical documentation
furnished with delivery actuators (schematics, overall dimensions and parts list).
