Specifications

  • Type: 2-Stage Heat Gas Valve
  • Gas Type: Natural Gas
  • Changeover: Manual
  • Series: Heatco
  • Voltage Rating: 24 VAC

Product Overview:
Provides controlled two-stage fuel delivery for residential heating equipment. The RESIDEO VR8305Q4195 2-Stage Heatco Gas Valve 24V manages low-stage and high-stage gas delivery according to the heating system's control requirements. Its combination valve design integrates fuel regulation and automatic shut-off within a single assembly, supporting stable combustion across varying heating demands.

Two-Stage Fuel Control:
Manages gas delivery across low-stage and high-stage heating operation. The valve responds to electrical control signals to establish the fuel flow required for the selected heating stage. This staged fuel control allows the heating system to adjust burner output according to changing heat demand.

Pressure Regulation:
Controls gas pressure supplied toward the burner system as part of the valve's integrated regulation assembly. The pressure-control mechanism supports consistent fuel delivery across the valve's operating stages. Stable gas delivery helps maintain the fuel conditions required for reliable burner operation.

Replacement Guidelines:
Replacing the 2-Stage Heatco Gas Valve is appropriate if it is damaged, malfunctioning, excessively worn, or otherwise deteriorated. Verify the RESIDEO part number VR8305Q4195 and the complete heating equipment model number before replacement. Replace the valve if deterioration affects two-stage fuel control, solenoid response, pressure regulation, shut-off operation, or normal heating performance.

Common Signs of Wear:

  • Main burner fails to ignite.
  • Low-stage operation becomes unreliable.
  • High-stage operation becomes inconsistent.
  • Burner flame becomes unstable.
  • Gas delivery becomes intermittent.
  • Valve fails to respond to control signals.
  • Burner shuts down unexpectedly.

Equipment Compatibility:
The RESIDEO VR8305Q4195 2-Stage Heatco Gas Valve is intended for heating equipment that specifies part number VR8305Q4195. Verify the complete heating equipment model number, control voltage, and manufacturer's parts documentation before purchasing to help confirm the correct application.
