Description
The Pietro Fiorentini Reval 182 is a pilot-controlled pressure regulator for medium and low pressure.
The PF 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 Reval 182 regulators are suitable for use with pre-filtered, non-corrosive gases.
