The Asco 8030G083 Solenoid Valve (8030G83) is a normally open, direct-acting solenoid valve designed for low-pressure air and water service. With no minimum pressure required and a 5.5 Cv flow factor, this valve is ideal for safety systems that require flow to remain open during power-off conditions.
