ASCO 8321A5 Solenoid Valve is a 1/4-inch NPT, 3-way quick-exhaust valve that vents pneumatic lines to atmosphere when energized, enabling rapid exhaust of downstream actuators without backflow into the supply. This HC8321A5 variant adds explosion-proof construction for operation in hazardous environments and is driven by a 125 V DC coil. The valve is part of ASCO’s 8321 family, with typical maximum operating pressure up to 200 psi and a 1/4-inch connection size, designed for pneumatic control applications where fast venting and safe performance in demanding settings are required.
