1. Proportional band includes outlet pressure drop plus hysteresis (friction), but does not include lockup.
2. Proportional band was determined with a pressure drop ranging from 50 to 150 psig / 3.4 to 10.3 bar. Approximately double the proportional band if the pressure drop is less than
50 psig / 3.4 bar.
3. With Type 112 restrictor set on 2.
4. The spring ranges for the Type 161AYW is 3 to 12 in. w.c. / 7.5 to 30 mbar.
5. The spring ranges for the Type 161AYW is 11 to 25 in. w.c. / 27 to 62 mbar.
6. The spring ranges for the Type 161AYW is 0.9 to 2.5 psig / 0.06 to 0.17 bar.
7. 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
