The Asco 8030G071 Solenoid Valve (8030G71) is a normally open, direct-acting solenoid valve designed for low-pressure service where flow must be maintained during power-off conditions. With a 1/2″ pipe size and 15 psi rating, it is ideal for venting, draining, or pressure-release functions in general-purpose air and water systems.
