Double-acting Pneumatic Actuator

GMK double-acting pneumatic actuator has a piston that is operated upon by air or liquid from both sides of the device. To open the valve, a larger pressure is given to one side. The opening and closing of the valve are determined by the flow of either air or liquid. GMK double-acting pneumatic actuator performs very well if significant torque loads are needed in either the forward or backward modes of motion. This actuator is also the standard in businesses that demand a powerful push, such as the oil and gas industries. It is used extensively in these fields.

Double-acting actuator work using the air pressure inside of a double-acting instrument. It causes the pistons to be forced away from one another, and then it forces them back together again. Because they need the use of supplied air, the operations of opening and closing that are included in this design are referred to as “double-acting.” This is accomplished by using the two built-in air intakes that are located on each side of the housing. 


  • It has the major advantage of springs, which is to give a fail position and is preserved in the double-acting design.
  • Even though the interface of the two types of actuator valves is typically the same, double-acting devices are significantly more lightweight, frequently less expensive, and frequently more compact in profile. It is especially true for larger sizes, as double-acting devices do not need to accommodate heavy springs.
  • When utilizing a double-acting system, the force required to stroke a valve open only needs to overcome the torque that is inherent to the valve and the process.
