Aperval 101 Pressure Regulator

Brand: Pietro Fiorentini S.p.A.
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.
The APERVAL 101 is a pilot-controlled regulator for low- and medium-pressure applications. The APERVAL 101 is a fail-to-open regulator.

It will open if:
  • There is no pilot loop supply;
  • The main pilot diaphragm is damaged.
This regulator is suitable for use with previously-filtered, non-corrosive gases.

Its truly "top entry design" allows all maintenance to be carried out without taking the body off  line.
Features
  • Design pressure: up to 17 bar (246.5 psig) for spheroidal cast iron version; up to 18.9 bar (274 psig) for cast steel version 
  • 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: 0.5 to 18.9 bar (7.25 to 274 psig) 
  • Range of outlet pressure Wd: 20 to 9,500 mbar (0.29 to 137.75 psig) 
  • Minimum working differential pressure: 480 mbar (6.96 psig) 
  • Accuracy class AC: up to 5 (according to operating conditions) 
  • Lock-up pressure class SG: from 10 to 30 depending on the outlet pressure 
  • Available size DN: 2”- 3”- 4” 
  • Flanging: class 125FF- 125RF- 150RF according to ASME B 16.1, and PN16 according to ISO 7005-2
