The Asco EF8030G003 Solenoid Valve (EF8030G3) is a direct-acting, normally closed valve built for low-pressure air, water, or inert gas service in hazardous environments. Its explosionproof design and zero-pressure differential capability make it ideal for venting, draining, or dosing applications in gravity-fed or minimal flow systems.
