Technical Data
Fluid: Compressed air
Inlet pressure range: 10 psig (0.7 bar) to 450 psig (31 bar) maximum*
* For best performance, inlet pressure should be at least 10 psig (0.7 bar) greater than the desired
regulated pressure, but must not exceed the specified maximum.
Operating temperature: 0° to 175°F (-20° to 80°C) **
** Air supply must be dry enough to avoid ice formation at temperatures below 35°F (2°C).
Typical flow with 100 psig (7 bar) inlet pressure, 90 psig (6.3 bar) set pressure and
15 psig (1 bar) droop from from set: 6.4 scfm (3 dm
3 /s)
Maximum bleed rate at 50 psig (3.5 bar) outlet pressure: 0.25 scfm (0.12 dm 3 /s)†
†Maximum bleed rate occurs under dead-end (no flow) conditions.
Pilot ports: 1/4" PTF, ISO G, or ISO Rc
R41 feedback port: 1/8" PTF, ISO G, or ISO Rc
Materials
Body, bonnet: Aluminum
Valve: Teflon
Elastomers: Nitrile
