Bulletin 71.1:SR5 W8966 Figure 2. Type SR5 Inlet Pressure Outlet Pressure Atmospheric Pressure Figure 3. Type SR5 Operational Schematic Introduction The Type SR5 regulator is a compact, large capacity, direct-operated pressure reducing regulator. It is designed for use in applications where a sanitary design is essential, such as pharmaceutical, biotech, or food and beverage industries.

Bulletin 71.1:SR5 Capacity Data The capacity information on the following pages is based on three offset factors, 10, 20 and 30 percent. Flow capacity at set point (set flow) was approximately 10% of maximum flow. Offset, or droop, is deviation from the setpoint of the regulator, and is usually stated in percentage of set point value. To evaluate the performance of a regulator, compare the stated capacities at equivalent operating pressures and offset factors.
Bulletin 71.1:SR5 For Non-Critical Pressure Drops Water Capacities For pressure drops lower than critical (absolute outlet pressure greater than one-half the absolute inlet pressure), use the following formula: All water capacities in Table 10 are in gallons per minute and liters per minute. Use the following equation to determine flow capacity for liquid relief valve sizing: 1 #G0 3). # '4 $0 $%' 0 where, Q = Gas flow, SCFH (60°F and 14.
