Spring return electric actuator.

All actuators have an internal heater for moisture control dual spdt switches and positive mechanical stops on larger models. These types of actuators are used in situations that require valves to automatically and immediately enter a safe position upon loss of power. With over 50 years of experience in the valve automation industry dresser natural gas solutions rcs offers a comprehensive line of quarter turn multi turn and the industry leading surepowr series of spring return electric actuators designed to address the most severe and demanding service requirements. A damper actuator or damper motor from grainger adjusts the flow of air though an hvac system.

It is available from 300 in lbs through 40 500 in lbs. 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. A non intrusive intelligent fail safe quarter turn actuator for on off and modulation control in fail safe applications.

That s why you ll find a wide range of actuator options here. The design has the ability to independently adjust motor speed and fail safe shutdown time. 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. Spring return electric actuators are used in critical processes to return quarter turn valves to their safe position even with the absence of power.

Belimo spring return actuators extensive torque offering 18 in lb to 180 in lb a vast selection of actuators for a wide range of applications. Spring return electric actuators. S 1300 spring return 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.

S 1300 spring return electric actuators product name. When power is supplied the spring mechanism is compressed to store energy for movement. True mechanical spring return providing the most reliable fail safe. The robust and compact mechanical spring return design can be triggered to fail safe action either on loss of power or signal.

The p series electric actuators is a quarter turn non spring return actuator that fails in place. Most actuators are available through the range of 12v to 230v.
