Product Description P/N: VR8440P2088
Description
The Honeywell VR8440P2088 is a dual automatic, step-opening combination gas valve designed to provide precise fuel regulation for intermittent pilot gas heating appliances. This component utilizes advanced servo-operated pressure regulation to deliver a controlled, low-pressure initial ignition before smoothly transitioning to a full firing rate. By preventing hard startups and managing continuous fuel flow, the valve ensures safe, highly efficient thermal performance in both residential and light commercial HVAC systems.

Information About VR8440P2088
The VR8440P2088 is an integral mechanical fuel controller compatible with standard 24 VAC intermittent pilot heating networks. It features a rugged, step-opening pressure regulator architecture that limits the initial gas supply to create a soft, reliable ignition sequence, effectively eliminating burner rollout and associated noise. HVAC technicians deploy this exact replacement part to manage natural gas distribution within furnaces, boilers, and heating units requiring seamless step-to-full-capacity modulation. The valve assembly includes a manual gas shutoff, two automatic operators, and built-in safety mechanisms that immediately halt fuel delivery in the event of pilot flame failure.
Key Features:
● Step-Opening Regulator: Delivers a controlled, low-pressure initial gas flow to ensure a smooth, quiet ignition before advancing to full capacity.
● Intermittent Pilot Design: Eliminates the need for a continuous standing pilot light, significantly reducing energy consumption during standby periods.
● Dual Automatic Valves: Features two internal safety shutoffs that instantly secure the gas line if the control module detects a loss of flame.
● 24 VAC Compatibility: Operates efficiently on standard 24-volt alternating current, integrating flawlessly with common HVAC control boards and thermostats.
● Manual Shutoff Dial: Includes an easily accessible top-mounted knob allowing technicians to safely isolate the gas supply during routine maintenance.
● Servo-Operated Diaphragm: Utilizes advanced mechanical pressure balancing to continuously maintain precise manifold gas pressure during active heating cycles.
● Standardized Connection: Equipped with standard NPT threaded inlet and outlet ports to facilitate rapid mechanical integration into existing commercial gas piping.
The VR8440P2088 delivers the reliability and precision required for exact fuel modulation and soft-ignition safety in modern intermittent pilot heating networks.
