Fairchild 10232 model 10 precision regulator

The Model 10 is designed for applications that require high capacity and accurate process control. A supply valve which is balanced by utilizing a rolling diaphragm, insures a constant output pressure even during wide supply pressure variations. Stability of regulated pressure is maintained under varying flow conditions through the use of an aspirator tube which adjusts the supply valve in accordance with the flow velocity. Specifications Supply Pressure 500 psig, , (3500 kPa) Maximum Flow Capacity 40 SCFM (68 m3 /HR) @ 100 psig, , (700 kPa) supply and 20 psig, , (150 kPa) setpoint Exhaust Capacity: 5.5 SCFM (9.35 m3 /HR) where downstream pressure is 5 psig, , (35 kPa) above 20 psig, , (150 kPa) setpoint Supply Pressure Effect: Less than 0.1 psig, , (.7 kPa) for 100 psig, , (700 kPa) change in supply pressure  Sensitivity: 1/8 in Water Column  Ambient Temperature: -40o F to +200o F, (-40o C to 93.3o C)  Hazardous Locations: Acceptable for use in Zones 1 and 2 for gas atmosphere; Groups IIA and IIB and Zones 21 and 22 for dust atmospheres  Materials of Construction  Body and Housing................................................Aluminum Diaphragms ...................
