PILOT-OPERATED GAS PRESSURE REGULATORS
Dixi
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.
