Spring Return Electric Fail Safe Actuators

Do rotork electric actuators have fail safe functionality.

Spring return electric fail safe 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. Device is capable of absolute position detection and configurable speed options. 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.

The p series quarter turn electric actuators are intended for ball valves butterfly valves and dampers. One of the big advantages of electric actuators over pneumatics is the ease and flexibility of installation scalability plus network communication controls and diagnostics. There are two types of fail safe electric actuators. When it comes to fail safe electric actuators there are a couple of options depending on torque requirements.

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. 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 actuators rely on mechanical energy stored by a spring to. Rts fail safe mechanical spring return electric actuator.

The design has the ability to independently adjust motor speed and fail safe shutdown time. When power is supplied the spring mechanism is compressed to store energy for movement. Failsafe options include spring return or battery backup. Available in 300 600 1200 and 1800 in lb units in both on off and modulating.

Our exmax product provides a quarter turn spring return failsafe solution. Spring return electric actuators and battery back up bbu actuators. Our cva cma products and waterproof iqt model through additional battery pack can all provide fail to position functionality. Failsafe electric actuators for all quarter turn applications spring return fq range actuators ensure automatic opening or closing even without any power supply.

Types of fail safe electric actuators. Explosion proof class i division 1 groups c d t4 design weatherproof type 4 4x. Spring return actuators up to 2 300 inch lbs of torque. Smart non intrusive electric fail safe quarter turn actuator with mechanical spring return ensures reliable shut down on loss of power or input command.

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.
