This will be accompanied by a slight residual outlet pressure of 1 to 4 inches H2O (2.5 to 10 millibar). Flow † Model SCFM 11-018 12 † 11-018-146, and 11-018-100: Typical flow with 100 psig (7 bar) inlet pressure, 60 psig (4.1 bar) set pressure and 0.125 psig (0.009 bar) droop from set. †† 11-018-110: Typical flow with 200 psig (14 bar) inlet pressure, 60 psig (4.1 bar) set pressure and 0.250 psig (0.017 bar) droop from set. Materials Body and bonnet: Zinc Main valve: Polycarbonate Main valve seat: PTFE Pilot valve: Stainless steel Pilot valve seat: Aluminum Main diaphragm: Nitrile Pilot diaphragm Low pressure models: 302 SS High pressure models: Nitrile Bottom plug: Brass Elastomers: Nitrile, CR, polyurethane Fluid: Compressed air Note: 5 micron prefiltration and oil-free air required. Inlet pressure range* Low Pressure Models: 8 to 150 psig (0.55 to 10.3 bar) High Pressure Models: 10 to 200 psig (0.7 to 13.8 bar) * Inlet pressure must be at least 7 psig (0.5 bar) greater than the adjusted outlet pressure for proper operation. Operating temperature**: 32°F to 160°F (0°C to 70°C) ** Air supply must be dry enough to avoid ice formation at temperatures below 35°F (2°C). Repeatability Low Pressure Models: 0.02 psig (0.001 bar) for flow change; 0.05 psig (0.004 bar) when turning supply off and on. High Pressure Models: 0.08 psig (0.006 bar) for flow change; 0.16 psig (0.011 bar) when turning supply off and on.
