Spring Return Electric Fail Safe Actuators

Device is capable of absolute position detection and configurable speed options.

Spring return electric fail safe actuators. Failsafe electric actuators for all quarter turn applications spring return fq range actuators ensure automatic opening or closing even without any power supply. There are two types of fail safe electric 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. Spring return actuators rely on mechanical energy stored by a spring to.

Types of fail safe electric actuators. 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. When power is supplied the spring mechanism is compressed to store energy for movement. Do rotork electric actuators have fail safe functionality.

Although they serve the same purpose they mainly differ in their operating principle. Spring return electric actuators and battery back up bbu 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. Our exmax product provides a quarter turn spring return failsafe solution.

Once the power is lost or removed the controlled. 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. Rts fail safe mechanical spring return electric actuator. Failsafe options include spring return or battery backup.

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

The l series linear electric actuators are typically used on gate valves globe valves control valves and dampers. The design has the ability to independently adjust motor speed and fail safe shutdown time. One of the big advantages of electric actuators over pneumatics is the ease and flexibility of installation scalability plus network communication controls and diagnostics. Our cva cma products and waterproof iqt model through additional battery pack can all provide fail to position functionality.

Spring return electric actuators are used in critical processes to return quarter turn valves to their safe position even with the absence of power.
