Spring Return Electric Actuator

How the damper will operate in the system is an important consideration when choosing damper actuators.

Spring return electric actuator.

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. These types of actuators are used in situations that require valves to automatically and immediately enter a safe position upon loss of power. Max torque 130 n m 1150 lb in standard weight 58 kg 127 lb w manual override weight 75 kg 164 lb mounting flange iso 5211 f10.

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. 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. 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. True mechanical spring return providing the most reliable fail safe.

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. It is available from 300 in lbs through 40 500 in lbs. Explosion proof class i division 1 groups c d t4 design weatherproof type 4 4x. Most actuators are available through the range of 12v to 230v.

The robust and compact mechanical spring return design can be triggered to fail safe action either on loss of power or signal. Spring return electric actuators are used in critical processes to return quarter turn valves to their safe position even with the absence of power. The p series electric actuators is a quarter turn non spring return actuator that fails in place. S 1300 spring return electric actuators.

All actuators have an internal heater for moisture control dual spdt switches and positive mechanical stops on larger models. When power is supplied the spring mechanism is compressed to store energy for movement. That s why you ll find a wide range of actuator options here. S 1300 spring return electric actuators product name.

A non intrusive intelligent fail safe quarter turn actuator for on off and modulation control in fail safe applications. The design has the ability to independently adjust motor speed and fail safe shutdown time.
