Resideo VR8300A4508 Valve

The Resideo VR8300A4508 is a professional-grade 3/4" 24VAC standing pilot dual automatic combination gas valve engineered for single-stage heating systems. This high-capacity dual safety shutoff gas valve is rated for 1/2 psi and supports a wide operational range from 30,000 to 290,000 BTUh. Designed with a straight-through body pattern and flange, it serves as a robust standing pilot ignition control replacement for legacy units. The integrated adjustable servo regulator maintains a precise 3.5" water column setpoint, ensuring consistent manifold pressure despite fluctuating inlet conditions. This Resideo VR8300 gas valve includes 1/4 inch quick-connect terminals and a 1/8" NPT pressure tap for efficient field diagnostics. For maximum versatility on the job site, the package contains two 3/4" x 1/2" reducer bushings and a natural-to-LP conversion kit. Wiring and adjustments are top-mounted for streamlined access in tight mechanical rooms, and the LITE-RITE (OFF-PILOT-ON) sequencing simplifies the lighting process for field technicians.
