Reval 182
Pilot-operated gas pressure regulators

Reval 182

The Reval 182 is a pilot-controlled pressure regulator for medium and low pressure.
The Reval 182 is a 'fail close' regulator, i.e. it closes 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 pre-filtered, non-corrosive gases.
