Description
The Honeywell V4944N1011 is a two-stage pressure regulating gas valve engineered for reliable, precise fuel control in commercial and industrial gas-fired heating applications. With a 1″ NPT connection and 120Vac operating voltage, this valve delivers dual-stage regulation to maximize combustion efficiency and system performance.
High Fire & Low Fire Regulation
The V4944N1011 features independent high fire and low fire regulator stages, allowing the burner system to modulate between two distinct firing rates for improved efficiency and reduced fuel consumption. Factory-set pressure points are calibrated for immediate installation and commissioning.

Two-Stage Operation Benefits
Two-stage gas valves allow heating systems to operate at a lower firing rate during mild demand conditions and ramp up to full capacity when needed. This staged approach reduces thermal cycling, extends equipment life, lowers operating costs, and improves overall system comfort and efficiency compared to single-stage operation.
