Apperflux 101 gas pressure regulator

The scope of this manual is to provide the essential information for the installation, commissioning, disassembly, re-assembly and maintenance of APERFLUX 101 regulators. It is also appropriate to provide a brief illustration of the main features of the regulator and of its accessories.

Main features

The APERFLUX 101 pressure regulator is a regulator for medium and high pressure. The APERFLUX 101 is a “fail open” type regulator and therefore opens in the event of: - rupture of the main diaphragm - no feed in the pilot circuit The main specifications of this regulator are:

• Design pressure: up to 85 bar (1232,8 Psi)
• Working temperature range: -20°C + 60 °C (-4 to + 140 °F)
• Ambient temperature: -20°C + 60 °C (-4 to + 140 °F)
• Inlet pressure range bpu: 1,8 to 85 bar (26,1 to 1232,8 Psi)
• Regulating range possible Wd: 0,8 ÷ 74 bar (11,6 to 1073,3 Psig) (depending on the pilot installed)
• Minimum differential pressure 1 bar (14,5 Psig). Recommended >2 bar (29 Psig)
• Precision class AC: up to 1 (depending on the operative conditions)
• Closing pressure class SG 10 (depending on the operative conditions) 

Pilot Operated

Pressure Regulators APERFLUX 101 use following type of pilots:

• 302/. setting range Wd: from 0,8 to 9,5 bar; (11,6 to 137,7 psig)
• 304/. setting range Wd: from 7 to 43 bar; (101,5 to 623,5 psig)
• 305/. setting range Wd: from 20 to 60 bar; (290 to 870,2 psig)
• 307/. setting range Wd: from 41 to 74 bar; (594,6 to 1073,3 psig)
