Reval 182

Reval 182 is one of the pilot-operated gas pressure regulators by Pietro Fiorentini.

This device is suitable for use with previously filtered non-corrosive gases, and it is mainly used for medium and low pressure natural gas distribution networks.

According to the European Standard EN 334, it is classified as Fail Close (pilot series 200/A) or Fail Open (pilot series 210/A) according to the installed pilot (except for the PM/182 monitor).

Reval 182 is Hydrogen Ready for NG-H₂ blending.
