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

Example: If a non-standard setpoint is needed, see the following example for instruction in using Table 8.

Non-standard setpoint = 140 mbar / 2 psig, then the factory set of the token relief will be 1.3*140 = 182 mbar /

2.6 psig. The factory OPSO and UPSO set values will be 165% of set and 50% of set, respectively, resulting is

values of 231 mbar / 3.4 psig and 70 mbar / 1 psig, also respective to OPSO and UPSO.
