The Resideo by Honeywell VR8300H4501 is a 24-volt standing pilot natural gas valve designed for residential and light commercial heating applications. This slow-opening valve features 3/4" NPT inlet and outlet connections and is rated for gas inputs up to 200,000 BTU, making it suitable for medium to large furnaces and heating systems.

Key Features:

• 24-volt AC operation for standard HVAC control compatibility
• Standing pilot ignition system design
• Slow opening function prevents pressure surges and flame roll-out
• 3/4" x 3/4" NPT threaded connections for easy installation
• 200,000 BTU maximum input capacity
• Natural gas application (NG only)

The VR8300 series combination gas valves integrate the gas shutoff, pressure regulation, and safety pilot functions into a single compact unit. The slow-opening characteristic helps ensure smooth, controlled ignition while reducing stress on system components. This valve is designed for use in systems with standing pilot ignition and requires proper thermocouple or pilot generator for safe operation.
