APA pneumatic controller is a pneumatic automatic control valve, operating by using air pressure to perform opening/closing operations or regulating the fluid in the pipeline. This is the optimal solution for systems that require fast response speed, stable operation, low cost and high durability.
Structure and operation:
Body: Made of high pressure die-cast aluminum alloy, anodized against corrosion.
Piston: Reciprocating motion creates rotational force through the camshaft.
Spring (for single acting type): Helps return the valve to its original position when the air is cut off.
Drive shaft: Transmits torque to the valve.
Mechanism of action:
Double acting: Opens and closes pneumatically in both directions.
Single acting: Opens by air, closes by spring force (or vice versa).
