Eclipse Combustion ES363 Ratio Regulator 1-1/2" NPT 5 PSI Max

Technical Features

• Balanced Double Diaphragm: The ES363 is engineered to operate over a wide range of inlet pressures with minimal impact on outlet pressure, ensuring stable combustion even as supply pressures fluctuate.

• 1:1 Ratio Control: As system air pressure increases through the loading line, the regulator opens to balance the gas outlet pressure, typically maintaining a slightly less than 1:1 ratio.

• Low-Fire Adjustment: Features a manual bias adjustment to fine-tune the gas flow during low-fire burner settings, allowing for a gas-rich or lean startup as needed.

• Versatile Compatibility: UL recognized and CE approved for use with natural gas, propane, and butane.
