Ordering information
Models listed include relieving diaphragm and PTF threads. Requires a pilot regulator (ordered separately).
ISO Symbols Port Size Model Flow† scfm (dm3/s) Weight lb (kg)
1-1/2" R18-B00-RNXA†† 2000 (944) 6.82 (3.09)
2" R18-C00-RNXA†† 2000 (944) 6.61 (2.99)
† Typical flow with 100 psig (0.7 bar) inlet pressure, 90 psig (6.3 bar) set pressure and a droop of 15 psig (1 bar) from set.
†† Do not use the R41 feedback pilot regulator to control outlet pressures at or less than 100 psig (7 bar). Use the 11-104 feedback pilot regulator at those pressures.
