The Asco 8222G076 Solenoid Valve (8222G76) is a pilot-operated, normally closed brass valve for low-pressure steam. The 1/2″ NPT connection supports a 2.5 Cv flow, ideal for moderate flow rates in compact lines. Rated to 353°F, this model handles high-heat conditions in sterilizers, autoclaves, and cleaning systems.
