Spring Return Electric Fail Safe Actuators

Spring return electric actuators and battery back up bbu actuators.

Spring return electric fail safe 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. Rts fail safe mechanical spring return electric actuator. Explosion proof class i division 1 groups c d t4 design weatherproof type 4 4x. Failsafe electric actuators for all quarter turn applications spring return fq range actuators ensure automatic opening or closing even without any power supply.

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. Smart non intrusive electric fail safe quarter turn actuator with mechanical spring return ensures reliable shut down on loss of power or input command. 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. 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.

Once the power is lost or removed the controlled. Spring return actuators rely on mechanical energy stored by a spring to. 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.

There are two types of fail safe electric actuators. Although they serve the same purpose they mainly differ in their operating principle. Available in 300 600 1200 and 1800 in lb units in both on off and modulating. The p series quarter turn electric actuators are intended for ball valves butterfly valves and dampers.

Our cva cma products and waterproof iqt model through additional battery pack can all provide fail to position functionality. Spring return actuators up to 2 300 inch lbs of torque. Types of fail safe electric actuators. The l series linear electric actuators are typically used on gate valves globe valves control valves and dampers.

Failsafe options include spring return or battery backup. Our exmax product provides a quarter turn spring return failsafe solution. Spring return electric actuators are used in critical processes to return quarter turn valves to their safe position even with the absence of power. The design has the ability to independently adjust motor speed and fail safe shutdown time.

These types of actuators are used in situations that require valves to automatically and immediately enter a safe position upon loss of power.
