Copeland Comfort Control (White Rodgers) 36H64-463 Natural LP 3/4 Inch 2Stage LP Gas Valve 24V

The Emerson 36H64-463 is a two-stage gas valve designed for use in natural gas or liquified propane (LP) fueled HVAC appliances, most commonly gas furnaces and boilers. It acts as a crucial control component that manages the flow of gas to the burner assembly.This valve features a two-stage operation. During ignition, it opens fully to allow a quick and reliable gas flow for starting the burner. Once ignited, the valve switches to a lower, modulated stage, providing a more controlled gas supply for efficient heating operation. The 36H64-463 boasts a versatile design with a 3/4-inch NPT connection for easy installation in most HVAC systems. It also includes an adjustable pressure regulator that allows for fine-tuning the gas pressure delivered to the burner, optimizing performance for different gas types and applications. With a wide operating temperature range of -40°F to 175°F, this valve can withstand various climate conditions. Additionally, it supports both 50Hz and 60Hz electrical frequencies, making it compatible with most power grids worldwide. The 300,000 BTU maximum regulatory capacity ensures the valve can handle the gas flow requirements of most residential and light commercial heating systems. The low operating voltage of 24V minimizes safety risks and simplifies integration with typical HVAC control systems. In summary, the Emerson 36H64-463 gas valve plays a vital role in safe, efficient, and reliable operation of natural gas or LP-fueled furnaces and boilers. Its two-stage operation, adjustable pressure regulation, and broad compatibility make it a versatile solution for various HVAC applications.
