1. Maximum pressure to prevent the casings from bursting during abnormal operation (leaking to atmosphere and internal parts damage may occur).
Table 3. Pilot Pressure Ratings
As the outlet pressure rises toward the outlet pressure
setting, it compresses the pilot diaphragm against the
pilot control spring and allows the pilot valve plug or
disk close. Loading pressure begins building on the
Type EZR diaphragm and plug assembly. The loading
pressure, along with force from the main spring,
pushes the diaphragm and plug assembly onto the
tapered-edged seat, producing tight shutoff.
—Low-pressure pilot with an outlet
pressure range of 6-inches w.c. to 7 psig
(15 mbar to 0,48 bar). Pilot bleeds (exhausts)
downstream through the sense (control) line.
Table 2. Outlet (Control) Pressure Ranges, Proportional Bands, and Pilot Control Spring Information
—The monitor version of the Type 161AY
pilot. The pilot bleed (exhaust) is isolated from the sense
(control) line. This pilot is used in monitoring systems
requiring an isolated pilot bleed (exhaust).
—High accuracy pilot with an outlet
pressure range of 5 to 350 psig (0,34 to 24,1 bar).
Pilot bleeds (exhausts) downstream through the sense
(control) line.
—The monitor version of the Type 161EB
pilot. The pilot bleed (exhaust) is isolated from the sense
(control) line. This pilot is used in monitoring systems
requiring an isolated pilot bleed (exhaust).
—Outlet pressure range of 14.5 to
435 psig (1,00 to 30,0 bar). The Type PRX/120 can be

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.
