FCR - Flow Control Regulators are double diaphragm spring balanced flow ratio control regulators that offer maximum control and fuel efficiency on gas-fired applications involving preheated air to the burners, or where burners fire against avarying back pressure. The FCR monitors air mass flow by means of a pressure differential across a POP Orifice Flow Meter. The signal from the POP is applied across the regulator large top diaphragm; pressure differential automatically compensates for back pressure. Lower matching "gas" diaphragm is connected to suit the application. Three smaller diaphragms are used within the regulator to balance out dynamic and static forces in the control system. The FCR holds a constant air/fuel ratio from cold start-up through hot air application. All control components are on the cold side of the system and are unaffected by high combustion air temperatures, minimizing cost and maintenance and permitting initial start-up adjustment to be made on cold air at the high fire condition and adjusting gas to the desired ratio. FEATURES Operating temperatures to 150°F Maximum inlet pressure: 2 psig Maximum air signal: 15'' W.C. Nominal air signal: 10'' W.C. Minimum air signal: 0.1'' W.C. Accuracy Low Flow: + 0.0 / - .04'' W.C. Full Flow: + 0.0 / - 0.4'' W.C. Turndown: up to 10:1 All units factory tested and sealed   APPLICATIONS Hot air burner systems: cover annealing furnaces, reheat furnaces, continuous kilns, glass tanks Varying back pressure systems: paper drying, atmosphere generators, periodic kilns, forced air dryers, lumber kilns   CAPACITY TABLE Model Number Pipe Size NPT SCFH Gas Flow @ 4.0" W.C.
