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.
Do rotork electric actuators have fail safe functionality.
Rts fail safe mechanical spring return electric actuator.
The design has the ability to independently adjust motor speed and fail safe shutdown time.
The p series quarter turn electric actuators are intended for ball valves butterfly valves and dampers.
Types of fail safe electric actuators.
Available in 300 600 1200 and 1800 in lb units in both on off and modulating.
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.
Although they serve the same purpose they mainly differ in their operating principle.
There are two types of fail safe electric actuators.
These types of actuators are used in situations that require valves to automatically and immediately enter a safe position upon loss of power.
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.
Spring return electric actuators and battery back up bbu 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.
Failsafe options include spring return or battery backup.
