The Asco 8221G011 Solenoid Valve (8221G11) is a pilot-operated, normally closed solenoid valve built for high-capacity water flow regulation. Featuring a 1 1/2-inch NPT pipe size and a 1 1/4-inch orifice, it delivers a Cv of 24, optimizing fluid movement while minimizing pressure loss. Its slow-closing function effectively reduces water hammer, making it a reliable choice for industrial and HVAC applications.
