Trane val04925 Natural Gas Valve 250000 Btu/h

Product Description

The TRANE val04925 is a natural gas valve rated at 250,000 BTU/h, designed for use in gas-fired heating equipment where reliable fuel control is required. It features a 0.50-inch inlet by 0.75-inch outlet NPT connection and operates on a 750-millivolt (mV) thermoelectric power system, making it compatible with millivolt standing-pilot heating systems that require no external electrical supply to the valve. This valve ships without side taps and without an LP conversion bushing kit. Licensed HVAC technicians and gas appliance service professionals handle installation and service of this component.

This valve is suited for residential and light-commercial natural gas heating applications where a 750mV standing-pilot control system is specified. Typical installations include gravity-style or fan-assisted gas furnaces, wall heaters, and floor furnaces that rely on a thermocouple or thermopile to power the gas valve directly. The absence of side taps and LP bushings means this unit is configured for natural gas service as-delivered, without field conversion.

Key Features

• 250,000 BTU/h capacity for high-output natural gas heating systems
• 0.50-inch inlet x 0.75-inch outlet NPT threading for standard gas piping connections
• 750mV thermoelectric operation — no external electrical supply required at the valve
• Configured for natural gas service; no LP conversion kit included
• No side taps — clean installation in applications where side-tap ports are not needed

Compatibility

Designed as an OEM-style replacement natural gas valve for millivolt standing-pilot heating systems requiring a 0.50-inch x 0.75-inch NPT valve rated at 250,000 BTU/h.

Installation Notes

Installation must be performed by a licensed gas fitter or HVAC technician in accordance with local codes and the International Fuel Gas Code (IFGC). Shut off the manual gas supply at the nearest upstream shutoff valve and allow the system to depressurize fully before disconnecting the existing valve. Verify inlet and outlet NPT thread sizes match the existing gas train before installation, and leak-test all fittings with an approved leak-detection solution after reconnecting the gas supply. Do not attempt LP conversion with this valve, as no bushing kit is included and it is not configured for propane service as shipped.
