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.
