1.
Damage to internal parts of the regulator may occur if outlet pressure exceeds the actual pressure setting by amounts greater than shown in this row.
2.
For outlet pressure settings to 25 psig only. For pressure settings over 25 psig, outlet pressure is limited by max. emergency outlet pressure of 45 psig.
3.
For outlet pressure settings to 350 psig only. For pressure settings over 350 psig, outlet pressure is limited by max. emergency outlet pressure of 550 psig.
4.
Leakage or bursting of pressure-containing parts may occur if outlet pressure exceeds these values.

Applies to both loading regulator and main regulator.
3.
Damage to internal parts of the regulator may occur if outlet pressure exceeds the actual pressure setting by amounts greater than those shown in this row. Loss of
loading pressure to main regulator diaphragm will reduce outlet pressure settings in proportion to the loss in loading pressure.
4.
For pressure settings to 46 psig. For higher-pressure settings, outlet pressure is limited by max. emergency outlet pressure of 66 psig.
5.
For pressure settings to 350 psig. For higher-pressure settings, outlet pressure is limited by max. emergency outlet pressure of 550 psig.
6.
Leakage or bursting of pressure-containing parts may occur if outlet pressure exceeds these values.
7.
Limited to this value by maximum emergency loading pressure of main regulator.
