The Itron B56 is a versatile pounds-to-pounds reducing regulator with internal relief, designed for applications requiring accurate regulation over a wide range of inlet and delivery pressures. A malleable iron valve body enables the B56 to handle inlet pressures of up to 1000 PSIG. The large diaphragm area (9 sq.in.) and level ratio (3.5 to 1) ensure accurate regulation for this type of regulator over an outlet pressure range of 5-60 PSIG.
