The l series linear electric actuators are typically used on gate valves globe valves control valves and dampers.
Spring return electric fail safe 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.
Once the power is lost or removed the controlled.
Spring return electric actuators and battery back up bbu actuators.
Failsafe options include spring return or battery backup.
Do rotork electric actuators have fail safe functionality.
Our exmax product provides a quarter turn spring return failsafe solution.
When power is supplied the spring mechanism is compressed to store energy for movement.
Rts fail safe mechanical spring return electric actuator.
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.
Types of fail safe electric actuators.
Spring return electric actuators are used in critical processes to return quarter turn valves to their safe position even with the absence of power.
Our cva cma products and waterproof iqt model through additional battery pack can all provide fail to position functionality.
The p series quarter turn electric actuators are intended for ball valves butterfly valves and dampers.
Although they serve the same purpose they mainly differ in their operating principle.
Explosion proof class i division 1 groups c d t4 design weatherproof type 4 4x.
Device is capable of absolute position detection and configurable speed options.
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.
Failsafe electric actuators for all quarter turn applications spring return fq range actuators ensure automatic opening or closing even without any power supply.
The design has the ability to independently adjust motor speed and fail safe shutdown time.
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.
There are two types of fail safe electric actuators.
Available in 300 600 1200 and 1800 in lb units in both on off and modulating.
These types of actuators are used in situations that require valves to automatically and immediately enter a safe position upon loss of power.
Spring return actuators up to 2 300 inch lbs of torque.
