ASCO Numatics 553SS631K000030 Pneumatic Solenoid Valve

ASCO Numatics Mark 55 Series 553SS631K000030 is a double direct solenoid, 3-position, 4-way pneumatic valve with a closed-center configuration that precisely directs air to a connected actuator via a plug-in base. It features 3/8" NPT pressure ports and operates on 110–120 VAC at 50–60 Hz, powered by two solenoids for independent actuation. The valve provides side cylinder ports with individual exhaust paths and is offered in configurations that include a plug-in base and a light indicator, enabling quick status visibility. Designed for compact, reliable control in automation systems, this valve ensures predictable neutral positioning and minimal cross-talk between ports, making it suitable for applications such as cylinder control, pneumatic actuators, and other closed-center fluid-power circuits.
