Aperflux 101
Pilot-operated gas pressure regulators

Aperflux 101

The Aperflux 101 is a pilot-controlled pressure regulator for medium and high pressure. Aperflux is a "fail open" regulator i.e. it opens in following conditions:
•    If the  main diaphragm fails;
•    If the  pilot diaphragm/s fail;
•    If the  pilot seat valve fails;
•    If there is no feed  to the pilot loop.
These regulators are suitable for use with previously-filtered non-corrosive gases.
