The Utica-Dunkirk 550002740 Gas Valve is designed to provide a consistent and accurate control of LP gas to the HVAC systems. It controls the gas pressure to 10” WC with the use of 24V power for steady combustion. The 3/4” inlet is the gas inlet that flows through the valve and exits through the 1/2” outlet to ensure that the burner is always on. This valve is especially used in furnaces and boilers that use liquid propane as a medium of operation. Advantages include increased energy saving, safer control of the gas, and better integration into the heating systems.
