Although they serve the same purpose they mainly differ in their operating principle.
Spring return electric fail safe actuators.
The design has the ability to independently adjust motor speed and fail safe shutdown time.
Rts fail safe electric actuators with true mechanical spring return for fail safe positioning are designed and field proven for reliable shutdowns on loss of power or signal.
Spring return electric actuators are used in critical processes to return quarter turn valves to their safe position even with the absence of power.
Fail safe spring return electric actuators more simply known as spring return electric actuators are used on linear and rotary valves in a range of applications across nearly all industrial process systems.
Do rotork electric actuators have fail safe functionality.
When it comes to fail safe electric actuators there are a couple of options depending on torque requirements.
Rts fail safe mechanical spring return electric actuator.

The l series linear electric actuators are typically used on gate valves globe valves control valves and dampers.
Sun yeh s series spring return electric valve actuators and tunnel damper valve actuator utilizes spring driven pinion and rack mechanism to provide torque ranges from 50n m to 260n m mechanical fail safe quarter turn electric actuators.
Once the power is lost or removed the controlled.
One of the big advantages of electric actuators over pneumatics is the ease and flexibility of installation scalability plus network communication controls and diagnostics.
When energized the actuator operates the valve normally and at the same time compresses the spring which is held in the loaded position by a solenoid brake.
