Accuracy

Inlet Sensitivity for Nitrile (NBR) and

Silicone (VMQ) Elastomers: Less than 0.2 psig /

14 mbar change in outlet pressure for every 25 psig /

1.7 bar change in inlet pressure

Inlet Sensitivity for Fluorocarbon (FKM) Elastomers: Less than 0.4 psig / 28 mbar change in outlet pressure for every 25 psig / 1.7 bar change in inlet pressure Repeatability for Nitrile (NBR) and Silicone (VMQ) Elastomers: 0.1 psig / 7 mbar(2)

Repeatability for Fluorocarbon (FKM) Elastomers:

0.3 psig / 21 mbar(2)

Air Consumption: Testing repeatedly shows no discernible leakage

Types 67CR, 67CSR, 67CFR and 67CFSR Internal

Relief Performance

Low capacity for minor seat leakage only, other overpressure protection must be provided if inlet pressure can exceed the maximum pressure rating of downstream equipment or exceeds maximum outlet pressure rating of the regulator.
