Table 8. Regulator and Slam-shut OPSO and UPSO Pressure Ranges

Example: If a non-standard setpoint is needed, see the following example for the proper use of Table 8.

Non-standard setpoint = 140 mbar / 2 psig, using the value presented above, the factory set of the token relief will be

1.3 x 140 = 182 mbar / 2.6 psig. The factory OPSO and UPSO set pressures are 165% and 50% of the non-standard

setpoint, respectively. The resulting settings are: OPSO = 231 mbar / 3.4 psig and UPSO = 70 mbar / 1 psig.

1. Standard factory set shown. Factory set is at the Minimum value of the range indicated. Range indicated is a percentage of Setpoint. Percentage indicated is based on the Set Pressure Range

in which that setpoint resides. If non-standard sets are required, adherence must be made to constraints shown in Table 7, including Token Relief Set Range, OPSO and UPSO set range and

Minimum Required difference between Token Relief and OPSO Set.

2. Minimum Token Relief values apply to -20 to 60°C / -4 to 140°F service temperatures. For service below -20°C / -4°F, add 8 mbar / 0.12 psig to the minimum Token Relief value listed.

3. Token Relief is not available for the Type CSB454.
