Working Principle of Hydraulic Actuators | Hydraulic ...
Hydraulic actuators use liquid pressure rather than instrument air pressure to apply force on the diaphragm to move the valve actuator and then to position valve stem.. Nearly all hydraulic actuator designs use a piston rather than a diaphragm to convert fluid pressure into mechanical force.. The high pressure rating of piston actuators lends itself well to typical hydraulic system pressures ...
