Brand: Pietro Fiorentini S.p.A.
Request Information
When requesting information, please download the Fillable PDF to provide details about your regulator use case. Instructions for completing the form are found in the footer of the document. Once completed, please upload the document with the Request for Information.
Aperflux 101 is a piloted-operated pressure regulator. Particularly suitable for high-pressure transmission systems and for medium pressure natural gas distribution networks, it can be used with previously filtered non-corrosive gases.

It is classified as Fail Open according to the European Standard EN 334.

Aperflux 101 is a boot style pilot-controlled pressure regulator for medium and high pressure applications.

Aperflux 101 is normally a failed open regulator and specifically will open under the following circumstances:
  • Breakage of main diaphragm
  • Lack of feeding to the pilot circuit
These regulators are suitable for use with previously filtered, non-corrosive gases.

Designed With Your Needs In Mind
  • Compact Design
  • Easy Maintenance - Top Entry
  • Low Noise
  • High Turn Down Ratio - High Accuracy
  • Low Operation cost
Features

  • Operating temperature: -10° to 60° C (14° to 140° F) 
  • Ambient temperature: -20° to 60° C (-4° to 140° F) 
  • Range of inlet pressure bpu: 3 to 85 bar (43.5 to 1,232.8 psi) 
  • Range of outlet pressure Wd: 2 to 74 bar (29 to 1,073.3 psig) depending on installed pilot 
  • Minimum working differential pressure: 1 bar (14.5 psi) - Recommended > 2 bar (29 psig) 
  • Accuracy class AC: up to 1 depending on the outlet pressure 
  • Closing pressure class SG: 10 depending on the outlet pressure 
  • Available size DN: 2” - 3” - 4” -Flanging: class 300-600 RF or RTJ according to ANSI B16.5
