The Asco 8215C073 Solenoid Valve (8215C73) is a direct-acting, normally open, 2-way solenoid valve built for continuous air-fuel gas flow in low-pressure combustion systems. With a robust aluminum body and a high Cv of 37, this valve provides exceptional capacity in applications where default-open operation is required until energization.
