Spring return type Pneumatic Actuator

GMK spring return actuator has one side of the piston supplied with air or liquid, while the other side of the actuator is driven by a spring to open and shut the valve. The fluid or air enters the piston from one side. To open and close the valve, a spring works against the force of the air or liquid passing through it. The design of a spring return type pneumatic actuator works very well because it can accommodate the one-sided torque load that is present during the activation stroke. In addition, when a quick shutdown is necessary for safety, a spring return is the optimal choice because of its simpler design and greater reliability. It is because a rapid shutdown is essential for safety.

GMK spring return-type actuators are able to be used for a wide variety of applications because of their adaptable design. These functions include, but are not limited to, the following:


  • Regulation dampers
  • System components for heating, ventilation, and air conditioning
  • devices that cut down on expenses
  • Terminals using Vacuum Alternating Current
  • Ventilation fans
  • Blade coverings
  • Medical apparatus that patients in hospitals use to assist them in breathing


Some additional benefits are; Security Because it is an authentic mechanical spring return, it offers the best possible level of protection.

It comes with a manual override crank so setting it up is quite easy.

Energy: A more efficient system with a smaller transformer may be achieved by reducing the amount of power that is used.

You can achieve efficient operation by maintaining consistently low operating temperatures and a stable operating voltage over the whole range. It results in peak performance.
