Will this work with Viton or EPR specific valves

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

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

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

Johnson Controls VG2831WN Valve Body Els PW 29614 and dangerous flue gas leakageThe 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.
