1. The pressure/temperature limits in this Instructional Manual and any applicable standard or code limitation should not be exceeded.

2. When using a Type SA/2 pilot supply lter regulator, the differential pressure across the regulator must be a least 45 psid / 3.1 bar d for optimum regulator performance.

3. Types PRX and SA/2 Fluorocarbon (FKM) elastomer is limited to 0°F / -18°C.

4. Maximum Operating Differential Pressure is 1400 psid / 96.5 bar d for NPS 1 / DN 25 EZHSO Series.

Pilot Descriptions

The EZH and EZHSO Series pressure-reducing

regulators include a PRX Series pilot mounted on

the main valve for pressure reducing or wide-open

monitoring applications. PRX Series pressure reducing

pilots have the ability to handle a wide range of

setpoints from 14.5 to 1160 psig / 1.00 to 80.0 bar.

Type PRX/120: Outlet pressure range of 14.5 to

435 psig / 1.00 to 30.0 bar. The Type PRX/120 can be

used as the pilot on single stage pressure reducing

regulators or as the monitor pilot or as the working

pilot in wide-open monitor systems.

Type PRX/120-AP: Outlet pressure range of 435 to

1160 psig / 30.0 to 80.0 bar. The Type PRX/120-AP

can be used as the pilot on single stage pressure

reducing regulators or as the monitor pilot or as the

working pilot in wide-open monitor systems.

Type PRX/125: Identical to the Type PRX/120 except

the restriction screw is removed. The Type PRX/125

can only be used as the monitor override pilot on

working monitor applications.

Type PRX/125-AP: Identical to the Type PRX/120-AP

except the restriction screw is removed. The

Type PRX/125-AP can only be used as the monitor

override pilot on working monitor applications.
