Bard HVAC 5651-164 Gas Valve

The Bard HVAC 5651-164 is a standard-opening, 24V natural gas valve designed for high-performance regulation in gas-fired heating equipment. Engineering for precision, this dual automatic combination control features a 1/2 inch inlet x 3/4 inch outlet configuration, facilitating high-capacity flow for industrial and commercial applications. As an OEM replacement gas valve, it ensures seamless integration with existing Bard control systems, maintaining factory-spec manifold pressure and burner ignition cycles. The normally closed design remains de-energized to prevent gas passage, opening only upon receiving a 24-volt signal from the thermostat or integrated control board. Constructed with a durable brass body, this Bard 5651-164 gas valve provides long-term resistance to corrosion and mechanical wear. For technicians performing field service, this valve is a direct-drop replacement for faulty Honeywell VR8205 series controls often found in Bard wall-mount units and furnaces, ensuring reliable pilot-to-main-burner transitions and stable combustion across varying inlet pressures.

• Direct OEM Compatibility: Specifically engineered as a genuine Bard HVAC replacement part for guaranteed fit and performance.
• 24V Low Voltage Design: Rated for standard 24V AC heating circuits, simplifying terminal connections for service technicians.
• Versatile Porting: Features a 1/2" NPT inlet and 3/4" NPT outlet, suitable for a wide range of gas line configurations.
• Reliable Safety Shutoff: Redundant internal solenoid design provides an immediate failsafe against gas leaks when the call for heat ends.
• Compact Footprint: Designed for easy installation in tight cabinets common in Bard wall-mount HVAC units.

What are the signs of a failing Bard 5651-164 gas valve?
Technicians typically check for a "no-fire" condition where the igniter glows but the main burner fails to light. Use a multimeter to verify 24V is present at the valve terminals; if voltage is present but the valve does not click or release gas, the solenoid coil or mechanical seat is likely compromised.

Can this valve be converted for Propane (LP) use?
The 5651-164 is factory-configured for natural gas systems. For LP applications, a specific conversion kit containing the correct spring and orifice must be installed to match the higher manifold pressure required for propane combustion.

Is the Bard 5651-164 a direct replacement for Honeywell VR8200 series?
Yes, in many Bard configurations, the 5651-164 serves as the manufacturer-recommended replacement for specific VR8205R and VR8205M models. Always verify the part number on the existing valve body before installation.
