Honeywell vr8300h4501/u Single Stage Standing Pilot Gas Valve 24V Ac 3/4 Inches X 3/4 Inches Slow Opening

Product Description

The Honeywell VR8300H4501/U is a single-stage, slow-opening gas valve designed for standing pilot ignition systems in residential and light commercial gas-fired appliances. This valve operates on 24 V AC and handles natural gas flow capacities ranging from 30,000 BTU/h up to 300,000 BTU/h, making it well-suited for furnaces, boilers, water heaters, and other heating equipment that fall within that output range. The inlet and outlet connections are each 3/4 inches, allowing for straightforward installation in standard gas supply lines. The valve body features a straight-through pattern with a flange, which simplifies alignment and mounting during service calls or new installations. HVAC technicians and gas appliance service professionals rely on standing pilot gas valves like this one to provide reliable, controlled gas delivery to burner assemblies. The slow-opening regulation type reduces pressure spikes at startup, which helps protect burner components and extend appliance service life. Built into this valve is a complete control package that includes a safety shutoff, a manual valve, two automatic operators, a pressure regulator, and a pilot adjustment. The Lite-Rite OFF-PILOT-ON lighting sequence makes pilot lighting straightforward for both technicians and end users. The valve is rated for a maximum operating pressure of 1/2 psi and a pressure rating of 1/2 psi or 3.5 kPa. It operates reliably across an ambient temperature range of 0 F to 175 F, covering virtually all indoor heating equipment environments. The VR8300H4501/U carries UL Component Recognition under MCCZ2.MH5323, CSA International certification 112395, and Australian Gas Association approval 4717, confirming it meets recognized safety and performance standards. This valve is a dependable replacement or OEM-equivalent part for single-stage standing pilot gas heating systems.
