Bulletin 71.1:67D Overpressure Protection Note The 67D Series regulators have maximum outlet pressure ratings that are lower than their maximum inlet pressure ratings. A pressure-relieving or pressure-limiting device is needed if inlet pressure can exceed the maximum outlet pressure rating. Types 67DR, 67DSR, 67DFR, and 67DFSR regulators have a low capacity internal relief valve for minor seat leakage only.
