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 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.
