The Asco 8210G034 solenoid valve (8210G34) is a pilot-operated, normally open valve built for dependable control of air, water, and light oil in mid-sized flow applications. It’s 1/2″ port and higher Cv of 4.0 offers efficient handling of moderate flows at pressures up to 150 psi. This is great for systems that require continuous flow when unpowered, such as tank-draining, venting, or filling processes.
