change in outlet pressure for every 25 psig
(1,7 bar) change in inlet pressure
0.1 psig (7 mbar)

Testing repeatedly shows
no discernible leakage
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.

1. The pressure/temperature limits in this Instruction Manual 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.
