ASCO Valve WP8321A1 Solenoid Valve

ASCO WP8321A1 Solenoid Valve is a compact, fast-venting control valve from ASCO’s 8321 (Series 321) quick-exhaust family, designed to rapidly vent a downstream pneumatic line to atmosphere when the coil is de-energized. The WP8321A1 variant carries a 24 V DC coil, enabling direct drive from standard control electronics. In typical configurations, it uses 1/4-inch connections and supports supply pressures from about 10 to 200 psi, making it compatible with common industrial compressed-air systems. As a quick-exhaust valve, it vents through an external orifice to achieve near-zero downstream pressure quickly, which can improve cycle times and provide fast release in automated sequences. The WP8321A1 is commonly deployed in applications across refining, chemical processing, and food and beverage processing where fast venting and reliable actuation are important, and it is designed for panel mounting in compact spaces.
