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.
