Our 400 Series (e.g., 4V400, 3A400) pneumatic directional control valves manage high-flow applications. With solenoid or air-piloted actuation and typically 1/2″ porting, these robust valves (commonly 3/2, 5/2, or 5/3 way) provide precise airflow control for larger pneumatic cylinders and actuators in demanding industrial automation and machinery.
