The Asco 8221G015 Solenoid Valve (8221G15) is a pilot-operated, normally closed solenoid valve engineered for high-capacity water flow control. With a 2 1/2-inch NPT pipe size and a 1 3/4-inch orifice, it delivers a Cv of 38, ensuring efficient fluid regulation with minimal pressure drop. The integrated slow-closing mechanism reduces water hammer, making it well-suited for industrial and HVAC applications.
