Application
This valve is a direct OEM replacement for Williams Comfort Products gravity wall furnaces and vented heaters that utilize a millivolt standing pilot control system. The standing pilot configuration keeps the pilot flame continuously lit, generating the small millivolt signal needed to hold the main valve open — eliminating reliance on household electrical circuits.
Why Choose a Millivolt Standing Pilot Valve?
Millivolt gas valves are trusted in gravity-fed and older-style heating systems for their simplicity and independence from external power. They are especially valuable in areas prone to power outages, as the heater can continue to operate as long as gas supply is maintained. The P323011 ensures a precise, safe gas shutoff when the pilot flame is extinguished, providing an important safety function.
