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.

Fail safe electric actuators. The design has the ability to independently adjust motor speed and fail safe shutdown time. Battery backup fail safe electric actuators for emergency shutdown applications. 1 stored electrical energy that can be used in place of the external power to power the motor. A non intrusive intelligent fail safe quarter turn actuator for on off and modulation control in fail safe applications.

The battery recharges automatically when re energized. The actuator is configurable to either fail close or fail open on loss of power supply. The robust and compact mechanical spring return design can be triggered to fail safe action either on loss of power or signal. Our exmax product provides a quarter turn spring return failsafe solution.

Spring return electric actuators and battery back up bbu actuators. When power is supplied the spring mechanism is compressed to store energy for movement. Torques up to 2640 in lbs. Constant torque curve with torques from 150 nm to 1 200 nm the spring is not operated during standard operation.

There are 2 basic ways of achieving fail safe functionality. 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. 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.

Failsafe electric actuators for all quarter turn applications spring return fq range actuators ensure automatic opening or closing even without any power supply. With their new fqm fail safe unit auma offer innovative and safe actuator solutions for automatic operation of valves in case of emergencies making use of stored mechanical energy. Corrosion resistant housing and enclosure type 4 4x 6 ip65. A fail safe electric actuator has a way of driving the actuator to the desired fail safe position when external power is unavailable.

Types of fail safe electric actuators. Once the power is lost or removed the controlled. There are two types of fail safe electric actuators.
