The Asco 8220G005 Solenoid Valve (8220G5) is a pilot-operated, normally closed valve engineered for precision in high-temperature water and steam systems. Its 3/4″ configuration, EPDM or PTFE options, and sturdy brass housing make it suitable for heavy-duty cycles in food equipment, sterilizers, and boiler systems that require elevated fluid temperatures.

Installation and Operational Notes
- Verify that the solenoid coil voltage exactly matches the system power.
- Depressurize the system and clean all internal piping before installation.
- Install a strainer or filter at the valve inlet as close as possible.
- Do not overtighten or allow piping to place stress on the valve body.
- Energize the coil a few times after wiring to confirm actuation by an audible click.
