The Asco 8030G082 Solenoid Valve (8030G82) is a normally open, direct-acting solenoid valve designed for low-pressure air and water service. With its full 3/4″ orifice flow path, 5 Cv rating, and zero-pressure actuation, it is well-suited for general-purpose venting, filling, or draining operations in control systems that require default-open functionality.
