ES Series is used where gas-to-air proportional flow is required. Gas flow is controlled as a function of the air pressure through a loading line that 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. Features include a valve seat design for consistent low fire repeatability; die-cast aluminum housing; corrosion-resistant internal components; inlet pressure tap with connector; and synthetic rubber diaphragms for low temperature performance.
