Normally closed upon power‑off: Spring‑return in normal state. The air circuit is cut off when de‑energized for enhanced safety and prevention of misoperation; no air supply output, ideal for applications requiring reset on power‑off.

Compact size, easy installation, low power consumption and low heat generation of the solenoid coil.

Simple control logic: Driven by a single coil instead of a double coil, with simple wiring and reduced electrical costs.

Fast switching response: Suitable for short‑time pulse actions, such as high‑frequency small cylinders, air blowing, clamping and unclamping.

1.Pneumatic clamping mechanism: The fixture clamps when powered on with air supply, and releases immediately upon power‑off for safety protection.

2.Air blowing & jet dedusting: Air blowing and chip removal for equipment. Air output when powered on, and blowing stops upon power‑off.

3.Control of small single‑acting cylinders (most common): Spring‑return cylinders extend when powered on and retract by spring force upon power‑off

4.Vacuum adsorption circuit: Controls vacuum on‑off. Vacuum is switched on when energized and cut off for vacuum breaking upon power‑off.

5.Safety protection circuit: Cut off air source on power‑off to prevent accidental extension of mechanisms during equipment shutdown.
