Description
Honeywell V8944B1035 Two Stage Pressure Regulating Gas Valve Overview
The Honeywell V8944B1035 is a two-stage pressure regulating gas valve engineered for reliable, precise control of natural gas in commercial and residential heating applications. With a 1-1/2″ pipe connection and 24VAC control voltage, this valve delivers accurate two-stage gas flow regulation to optimize burner performance, improve combustion efficiency, and reduce fuel consumption.
Two-Stage Regulation for Optimized Combustion
Designed for two-stage burner systems, the V8944B1035 independently regulates high-fire and low-fire outlet pressures. The high-fire regulator is field-adjustable between 3″ and 4.5″ water column (W.C.), with a factory setting of 3.5″ W.C. The low-fire regulator is adjustable between 0.8″ and 2″ W.C., with a factory setting of 0.8″ W.C. This dual-stage control allows the burner to operate at a reduced capacity during low-demand periods, maximizing efficiency and extending equipment life.
