PF Aperflux 101 Pilot-Operated Gas Pressure Regulators

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.

Functional Features*:

• Maximum inlet pressure: Up to 1,233 PSIG
• 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
