A storage tank can be added to the betrayal of the pneumatic actuator. The gas of the gas source must first enter the storage tank before it can enter the actuator.This method is better for valves with larger models or requiring more gas. Add a storage tank The role of the method is not to increase the pressure of the inlet gas source, but to make the source of the pressure tend to temperature.The principle of this method is that the inlet pipe is small, and then the gas source supply cannot keep up, resulting in a situation where the pressure is reduced. Ways and methods can allow important valves to have emergency gas source reserves.

Pneumatic actuator future technology development trend

If the switch is required to be faster, you can take the gas through the pipeline to be thicker, so that the gas intake will increase, the switch will naturally be faster


Install an accelerator.

In fact, when the valve is equipped with a pneumatic actuator, the switching time requirements of the valve should be considered. Under the premise of considering an all, if you consider the intake and exhaust speed of the pneumatic actuator, you can choose on the choice of exhaust pipe Larger pipe diameter.

Pneumatic actuators are actuators that use pneumatic pressure to drive opening and closing or regulating valves. They are also called pneumatic actuators or pneumatic devices, but they are generally known as pneumatic heads.

Pneumatic actuators are sometimes equipped with corresponding auxiliary devices. Commonly used are valve positioner and handwheel mechanism. The role of the valve positioner is to use the feedback principle to improve the performance of the actuator, so that the actuator can achieve accurate positioning according to the control signal of the controller.

The function of the handwheel mechanism is that when the control system fails due to power failure, gas failure, controller output or actuator failure, it can directly control the control valve to maintain the normal production.
