ASCO 8266C239V Solenoid Valve

ASCO 8266C239V is a 3/4-inch NPT, two‑way normally closed solenoid valve designed for fuel oil shutoff in burner systems and heating equipment. It features a rugged brass body with Viton seals and a lever‑actuated solenoid, plus a bypass port (W/BYPASS) for controlled secondary flow or purge in fuel lines. The valve is driven by a 120 VAC coil and offers a flow coefficient of 1.2 Cv, with a pressure range from 0 to 160 psi, enabling reliable shutoff and fuel delivery in mid‑pressure oil systems. Its standard 3/4" NPT connections and compact inline form factor support straightforward installation in existing fuel oil manifolds. Applications include commercial boilers and furnaces, with compatibility for common fuel oils such as #2 and #4 grades, where Viton seals resist the chemical exposure and elevated temperatures typical of heating oil service.
