ASCO 8220G9-24V Solenoid Valve Refrigerant Durable Material Construction: Synthetic EPDM

Durable Material Construction: Synthetic EPDM diaphragm resists thermal degradation in steam and hot water applications

making it a staple for technicians maintaining HVAC gas ignition systems

and the necessary wiring harnesses to ensure seamless boiler control system integration

provided the mounting plate and insertion depth align with your duct specifications

the MZS4 is designed for the standard 24Vac 3-wire (PO/PC) and 2-wire spring return actuators used in most modern zoning layouts

ASCO 8220G9-24V Solenoid Valve Refrigerant Durable Material Construction: Synthetic EPDMThe ASCO 8220G9 24V is a high performance, 2 way normally closed solenoid valve specifically engineered for demanding steam and hot water service. Featuring a robust brass body and an 1 1 4" NPT connection, this pilot operated solenoid valve provides a high flow coefficient of 15 Cv, ensuring efficient fluid control in industrial boiler systems and laundry equipment. Designed for versatility, it manages operating pressure differentials from 5 to 50
