Eclipse Ratio Regulator, ES Series
The ES-Series Ratio Regulators are used in applications where gas to air proportional flow is required. The gas flow 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 pressures balance. As the load line pressure increases, the ratio of the outlet pressure to the load line pressure will be slightly less than 1:1.
The ratio regulators are designed to optimize performance as ambient temperature and inlet pressure vary.
Features include:
• UL recognized and CE approved for natural gas,
propane, and butane.
• Valve seat design for consistent low fire
repeatability.
• Balanced double diaphragm design allows regulator
to operate over a wide range of inlet pressures while
minimally affecting outlet pressure.
• Rugged die cast aluminum housing.
• Corrosion resistant internal components.
• Synthetic rubber diaphragms for excellent low
temperature performance.
• Inlet pressure tap with connector (1-1/2", 2" & 3"
NPT (Rp) models only).
