STANDARD SPECIFICATIONS (for products on this page):
Ambient/Media Temperature: 40° to 125°F (4° to 52°C).
Body: Aluminum.
Dome and Knob: Acetal.
Fluid Media: Compressed air.
Inlet Pressure: 300 psig (20.7 bar) maximum.
Outlet Pressure: Adjustable up to 100 psig (6.9 bar). Pressure Gauge: 0 to 160 psig (0 to 11 bar); 1/8 NPT gauge
ports front and rear.
Panel Mounting: 1-3/16 inch (30 mm) hole required.
Seals: Nitrile.
Threads: NPT standard, BSPP. For BSPP threads, add a “C”
prefix to the model number, e.g., C5212C1004.
Precision Regulators have a small valve seat and a large diaphragm
area, a combination that allows greater precision, sensitivity, adjustment
resolution, and less variation in regulated pressure.
Relief Valves have maximum relief flows of 10 to 20 scfm (4.7 to 9.4 l/s).
For models with increased sensitivity at lower pressure, consult ROSS.
