ASCO WP8316A66 Solenoid Valve Two-Way One-Half Inch NPT 120V AC

ASCO WP8316A66 is a 1/2-inch NPT, 120 V AC solenoid valve from ASCO’s 8316 series, designed as a three‑port, pilot‑operated diaphragm valve that delivers high flow for industrial automation. Built with a brass body and Buna‑N seals, it operates as a pilot valve that directs pressure to a downstream actuator while venting the exhaust port, enabling fast actuation of pneumatic cylinders or larger control valves. The valve is configured for 1/2" NPT connections and typically features three ports (pressure inlet, actuator output, and exhaust), making it well suited for air and water service in manufacturing, packaging, and process lines. The WP8316A66 variant is part of the 8316 family, which is recognized for robust construction and reliable performance in high‑flow applications, with coil options that include 120 V AC (60 Hz) and compatibility with related 50 Hz configurations in various model lines. In practical use, engineers deploy this type of valve to pilot larger actuators or to provide a controlled sensing/exhaust path in automated systems, helping to achieve precise, rapid cycling of downstream equipment. Overall, the WP8316A66 offers a compact, durable solution for high‑flow switching and actuator piloting in demanding industrial environments.
