67D Series Pressure Reducing Regulators - 2

Bulletin 71.1:67D Introduction The 67D Series regulators are typically used to deliver constant reduced pressure of gaseous fluids to pilot-operated controllers and other pneumatic instrumentation. As shown in the Available Configurations table, an assortment of regulators is available to meet diverse flow requirements. Features • Compact—The 67D Series regulators are engineered for outstanding performance in a compact, lightweight package. • Smart Bleed™—Opens to exhaust downstream pressure when inlet pressure drops below outlet pressure. Recommended for dead-end service. • ...

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. Other overpressure protection must be provided if the maximum inlet pressure can exceed the maximum pressure rating of the downstream equipment or exceeds maximum outlet pressure rating...
