The 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 pressure feeding the pilot circuit;
These regulators are suitable for use with previously filtered, non-corrosive gases.

• Range of downstream pressure:  From 1,170 PSIG – depending on installed pilot
• Minimum working differential pressure: 14.5 PSIG
• Minimum ambient temperature:  Execution up -40°F
• Maximum ambient temperature:  140°F
• Flowing gas temperature:  -4°F to 140°F
• Accuracy class AC:  Up to 1.5% Gauge
• Look-up pressure class SG:  Up to 2.5% Gauge
