Spring Return Electric Fail Safe Actuators

When power is supplied the spring mechanism is compressed to store energy for movement.

Spring return electric fail safe actuators.

Rts fail safe mechanical spring return electric actuator. Spring return electric actuators and battery back up bbu actuators. There are two types of fail safe electric actuators. 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.

Although they serve the same purpose they mainly differ in their operating principle. 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. When it comes to fail safe electric actuators there are a couple of options depending on torque requirements.

The p series quarter turn electric actuators are intended for ball valves butterfly valves and dampers. These types of actuators are used in situations that require valves to automatically and immediately enter a safe position upon loss of power. The design has the ability to independently adjust motor speed and fail safe shutdown time. Once the power is lost or removed the controlled.

Our exmax product provides a quarter turn spring return failsafe solution. Do rotork electric actuators have fail safe functionality. Failsafe electric actuators for all quarter turn applications spring return fq range actuators ensure automatic opening or closing even without any power supply. The l series linear electric actuators are typically used on gate valves globe valves control valves and dampers.

Spring return electric actuators are used in critical processes to return quarter turn valves to their safe position even with the absence of power. Spring return actuators up to 2 300 inch lbs of torque. Our cva cma products and waterproof iqt model through additional battery pack can all provide fail to position 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.

Explosion proof class i division 1 groups c d t4 design weatherproof type 4 4x. 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. 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. Available in 300 600 1200 and 1800 in lb units in both on off and modulating.
