Eclipse Combustion India Ltd provides Ratio Regulators Valve, ES-Series. The product Ratio Regulators Valve are used in applications where gas to air proportional flow is required. The gas flow in the Ratio Regulators Valve is controlled as a function of the air pressure through a loading line which connects into the top of the regulator. As the system air pressure increases, it forces the Ratio Regulator Valve to open causing the outlet pressure to increase until the two pressure balances. The load line pressure increases the ratio of the outlet pressure. Load line pressure in the Ratio Regulators Valve will be slightly less than 1:1. Ratio Regulators Valves have a bias adjustment for varying the gas flow when setting the burner at low fire. Ratio Regulators Valves can be used to increase or decrease the gas flow resulting in gas rich or lean combustion. The adjustment is restricted in the gas rich direction therefore limiting the gas flow at zero air pressure. Ratio Regulators Valves are designed to optimize performance as ambient temperature and inlet pressure vary. The salient features of the Ratio Regulators Valve:
