1. Proportional band and Accuracy Class include outlet pressure drop plus hysteresis (friction), but do not include lockup.
2. Proportional band was determined with a pressure drop ranging from 50 to 150 psig / 3.5 to 10.3 bar. Approximately double the proportional band if the pressure drop is less than
50 psig / 3.5 bar.
3. With Type 112 restrictor set on 2. With Type PRX restrictor turn the restrictor screw one turn counterclockwise from fully seated.
4. Should only be used as the intermediate reduction pilot on the Type EZR worker/monitor systems.
5. Proportional band was determined with a pressure drop ranging from 100 to 300 psig / 6.9 to 20.7 bar. Approximately double the proportional band if the pressure drop is less than
100 psi / 6.9 bar.
