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 fail safe actuators.
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.
Although they serve the same purpose they mainly differ in their operating principle.
The p series quarter turn electric actuators are intended for ball valves butterfly valves and dampers.
The design has the ability to independently adjust motor speed and fail safe shutdown time.
Available in 300 600 1200 and 1800 in lb units in both on off and modulating.
When power is supplied the spring mechanism is compressed to store energy for movement.
When it comes to fail safe electric actuators there are a couple of options depending on torque requirements.
Spring return actuators up to 2 300 inch lbs of torque.
Spring return electric actuators and battery back up bbu actuators.
Smart non intrusive electric fail safe quarter turn actuator with mechanical spring return ensures reliable shut down on loss of power or input command.
There are two types of fail safe electric actuators.
The l series linear electric actuators are typically used on gate valves globe valves control valves and dampers.
Once the power is lost or removed the controlled.
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.
Failsafe options include spring return or battery backup.
One of the big advantages of electric actuators over pneumatics is the ease and flexibility of installation scalability plus network communication controls and diagnostics.

Rts fail safe mechanical spring return electric actuator.
Types of fail safe electric actuators.
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.
Our cva cma products and waterproof iqt model through additional battery pack can all provide fail to position functionality.
These types of actuators are used in situations that require valves to automatically and immediately enter a safe position upon loss of power.
Spring return electric actuators are used in critical processes to return quarter turn valves to their safe position even with the absence of power.
Do rotork electric actuators have fail safe functionality.
Device is capable of absolute position detection and configurable speed options.
