and gravity-fed heating systems

it is not a substitute for a dedicated backflow preventer like the Watts 288A series

verify your specific boiler’s wiring schematic for its line voltage terminal configuration

it serves as a critical safety component by monitoring internal heat levels and interrupting the burner circuit if temperatures exceed safe operational parameters

Critical Safety Compliance: Restores factory-specified hot surface ignition timing for safe burner startup

Johnson Controls VG2831WN Valve Body Els PW 29614 and gravity-fed heating systemsThe Johnson Controls VG2831WN is a heavy duty, 5 inch 3 way mixing globe valve engineered specifically for high capacity flow control in commercial HVACR and industrial applications. This ANSI Class 125 flanged unit is built with a rugged cast iron body and durable brass trim, providing long term reliability when managing hot water, chilled water, or 50% glycol solutions. With a high flow coefficient (238 Cv) and a modified linear flow characteristic,
