Honeywell V4944B1075 Diaphragm Gas Valve 2 Stage Pressure Regulating Slow Opening 1" NPT 30" Wires

The Honeywell V4944B1075 Diaphragm Pressure Regulating Gas Valve Slow Opening 1" NPT 30" Wires is a fuel control assembly used to manage gas flow and staged pressure regulation within combustion equipment. It opens using a diaphragm system gradually to ensure controlled fuel delivery and stable ignition conditions. Installed in burner and heating assemblies, it supports two-stage operation for efficient combustion control and proper transition between firing levels. Equipment intended for use in HVAC systems relies on this valve for regulated gas modulation, safe ignition sequencing, and consistent combustion performance during heating cycles.
