Spring Return Actuator

Using air or liquid the pressure is dispersed on both sides of the piston to move it in the direction you desire.

Spring return actuator.

Most types of valves will require one of two types of actuators to use. This configuration uses pneumatic or hydraulic pressure of the air or liquid to open or close the valve and a spring affects the opposite motion. Instead of having a spring the double actuator has ports at each end of the actuator. A full range of spring return actuators from 20 lb in.

Neles spring return vd series diaphragm type linear actuators are designed for use in both modulating control and on off service. These actuators offer an extremely long cycle life and are well suited to operate linear valves with small to medium thrust requirements. 2 position 100 250 vac sr. Spring boot 2 x actuator.

Spring boot 1 x actuator. The new 35 lb in. Unlike the spring return actuator the double acting actuator operates in both directions. The simple solenoid is a good example of a spring return actuator with the solenoid plunger being.

Belimo hvac damper actuators are designed for use in a wide variety of on off modulating or communicating damper and life safety applications. With the release of spring boot 2 actuator has been redesigned and new exciting endpoints were added. What is an actuator. The spring return also known as the single acting actuator and the double acting actuator.

Spring return actuators have air or liquid supplied to only one side of the piston and the energy to move the mechanisms comes from a spring on the opposite side. Spring return direct coupled actuators dca used in heating ventilating and air conditioning hvac systems to drive a variety of quarter turn final control elements requiring spring return fail safe operation. B series ductile iron w stainless steel cylinders c series ductile iron w carbon steel cylinders spring return and double acting actuators quarter turn output torques to 158200 nm. A spring return actuator is a control device that supplies one way powered motion with the impetus for its return stroke being supplied by a spring.

We split this guide into three main sections. To 160 lb in make siemens openair damper actuators the ideal oem choice for economizer damper roof top unit and air handling unit control. Gpc series actuator provides long lasting economizer control in a small footprint. While there are a variety of other types and categories of actuators these two are the most important and are frequently the go to choice for use in facilitating the operation of a great variety of machines and industrial mechanisms.
