Data Sheet

Bulletin 71.1:67C
2
1. The pressure/temperature limits in this Bulletin and any applicable standard or code limitation should not be exceeded.
2. Repeatability is the measure of the regulator’s ability to return to setpoint consistently when traveling from steady state to transient to steady state.
3. Silicone (VMQ) is not compatible with hydrocarbon gas.
4. Product complies with the material requirements of NACE MR0175. Environmental limits may apply.
5. Do not use in high aromatic hydrocarbon service.

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

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.
