ASCO 8040HB Solenoid Valve

ASCO 8040HB Red Hat solenoid valve is a 2‑way, normally closed, direct‑acting gas shutoff valve built for 3/8" NPT piping and an aluminum body. It belongs to ASCO's 8040 Red Hat family and is used as a pilot or main gas control in burners, ovens, generators, and other gas‑fired equipment. It provides a Cv of 1.2, an orifice of 5/16" (about 8 mm), and a gas capacity of roughly 64,400 BTU/hr at zero differential pressure, with a specified operating differential of 0–15 psi. The coil is available in common AC voltages, and the 8040HB listing notes a 110/120 V coil. Typical installations use 3/8" NPT connections, meeting standard safety shutoff requirements in commercial and industrial gas systems. Applications include commercial cooking equipment, heating appliances, and other gas‑fired gear that require reliable, code‑compliant shutoff control.
