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
