SMC AQ400 Inline Pneumatic Quick Exhaust Valve

SMC AQ400 Inline Pneumatic Quick Exhaust Valve is part of SMC's AQ series, delivering rapid exhaust of actuator air to atmosphere to speed up cylinder return and shorten cycle times in pneumatic automation. The AQ series is designed with high flow in a compact, lightweight body and is available in lip, diaphragm and inline body shapes, with inline models featuring built-in one-touch fittings for easy piping. Within the AQ400 family, variants such as AQ400-02 and AQ400-04 provide different port configurations to fit a range of circuit needs, enabling quick exhaust in compact spaces. Typical applications include accelerating actuation in packaging, material handling, robotics, and general manufacturing lines by efficiently venting exhaust without adding external plumbing.
