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.
