Bulletin 71.1:67C
3
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 is not compatible with hydrocarbon gas.
4. Product complies with the material requirements of NACE MR0175. Environmental limits may apply.

Accuracy
Inlet Sensitivity: Less than 0.2 psig (0,014 bar)
change in outlet pressure for every 25 psig
(1,72 bar) change in inlet pressure
Repeatability: 0.1 psig (0,0069 bar)
(2)
Air Consumption: testing repeatedly shows
no discernible leakage
Type 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.
