Fail Safe Spring Return Electric Actuator

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 actuator.

Once the power is lost or removed the controlled. Although they serve the same purpose they mainly differ in their operating principle. There are two types of fail safe electric actuators. The actuator can be controlled by external controller to open close and stop at any position between 0 and 90 degree and will fail clockwise to the end position on loss of power.

Smart non intrusive electric fail safe quarter turn actuator with mechanical spring return ensures reliable shut down on loss of power or input command. Based on the standard running direction that the actuator fails clockwise on loss of power. 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. Types of fail safe electric actuators.

When power is supplied the spring mechanism is compressed to store energy for movement. Our exmax product provides a quarter turn spring return failsafe solution. 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. Our cva cma products and waterproof iqt model through additional battery pack can all provide fail to position functionality.

Available in 300 600 1200 and 1800 in lb units in both on off and modulating. The robust and compact mechanical spring return design can be triggered to fail safe action either on loss of power or signal. Device is capable of absolute position detection and configurable speed options. The design has the ability to independently adjust motor speed and fail safe shutdown time.

Rts fail safe mechanical spring return electric actuator. Spring return electric actuators and battery back up bbu actuators. Explosion proof class i division 1 groups c d t4 design weatherproof type 4 4x. The electric spring return actuator uses an electric motor to drive a series of gears to rotate a drive shaft counter clockwise or clockwise depending on the desired fail safe position.

A non intrusive intelligent fail safe quarter turn actuator for on off and modulation control in fail safe applications. Spring return actuators rely on mechanical energy stored by a spring to. Do rotork electric actuators have fail safe functionality. 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.
