The ASCO 8220G11 (often cataloged as 8220G011) is a 2‑way, normally closed solenoid valve engineered for hot water and steam service, with 1-1/2" NPT pipe connections and a 1-1/4" orifice. The brass body carries EPDM seals and delivers a Cv of 22.5 for high flow in a 1-1/2" line, with a maximum differential pressure rating up to 150 psi in suitable service. Coil voltages available include 120/60 VAC and 110/50 VAC, compatible with standard control circuits. Typical applications include boiler feed, heating systems, and other hot water or steam flow-control tasks requiring rapid shutoff and reliable operation in industrial environments.
