Fail Safe Electric Linear Actuator

The design has the ability to independently adjust motor speed and fail safe shutdown time.

Fail safe electric linear actuator.

Fail safe actuators typically have two settings. Constant torque curve with torques from 150 nm to 1 200 nm the spring is not operated during standard operation. True mechanical fail safe 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. Avc is the industry leader when it comes to fail safe electric actuators for emergency shutdown esd and other fail safe applications.

The clear advantage of a mechanical fail safe system in electric actuators is this elimination of the actuator s electrical system and the fail safe system is 100 mechanical and specifiers feel more secure with this than trusting batteries or electronic components which can fail. They can be set to fail open where the valve automatically reverts to the open position when power to the actuator is lost. The robust and compact mechanical spring return design can be triggered to fail safe action either on loss of power or signal. The original product line of triac electric actuators e series electric actuators offer torques from 300 to 30 000 in.

Fail safe electric actuators electrical power supply with emergency shutdown at loss of power or signal. Our cva cma products and waterproof iqt model through additional battery pack can all provide fail to position functionality. A non intrusive intelligent fail safe linear actuator for on off and modulation control in fail safe applications. 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.

Once the power is lost or removed the controlled. Do rotork electric actuators have fail safe functionality. Fail safe actuators possess a mechanism that stores energy to drive the actuator to a predetermined safe position when power loss is detected. When power is supplied the spring mechanism is compressed to store energy for movement.

Our exmax product provides a quarter turn spring return failsafe solution. 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.
