Accurate pressure control and easy maintenance with the Reval 182

The Reval 182 is a pilot-controlled pressure regulator for medium and low pressure applications. The Reval 182 is normally a fail to close regulator that will close under the following conditions:

  • breakage of main diaphragm
  • lack of gas feeding to the pilot loop

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

The modular design of the Reval 182 pressure regulator allows retrofitting of an emergency monitor PM/182 or slam shut valve and/or silencer on the same body. The Reval 182 regulator is truly a “top entry design” which allows easy maintenance and/or retrofitting options in the field. The unique dynamic balancing system ensures an outstanding turn down ratio combined with an extremely accurate outlet pressure control.
