Pilot-operated gas pressure regulators


Dixi is pilot-controlled pressure regulator for medium and low pressure. Dixi is a "fail close" regulator i.e. it will close if :
•    The main diaphragm fails
•    The  pilot diaphragm/s fail
•    There is no feed  to the pilot loop.
These regulators are suitable for use with previously-filtered, non-corrosive gases.
