Pietro Fiorentini Pilot-Operated Gas Pressure Regulator Reval 182

  • Reval 182 is pilot-controlled pressure regulator for medium and low pressure applications.

  • Reval 182 is normally a fail to close regulator and specifically will close under the following conditions: breakage of main diaphragm and lack of feeding to the pilot loop.

  • This regulator is suitable for use with previously filtered, non-corrosive gases.

  • Available pipe sizes: 1″ to 10″ NPT

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.
