Internal Pressure Relief Valve Performance for Models 67DR, 67DSR, 67DFR, and 67DFSR
For low-capacity models only, where seat leakage is not significant; if inlet pressure may exceed the maximum rated pressure of
the downstream equipment, the internal pressure relief valve performance is limited to the following
exceed the maximum rated pressure of the downstream equipment or the maximum rated outlet pressure of the regulator, then the
pressure relief valve must be
If the inlet pressure may exceed the maximum rated pressure of downstream equipment or the maximum rated outlet pressure of the
regulator, additional overpressure protection must be provided.
