Pietro Fiorentini Reflux 819 Regulator

Reflux 819 is a pilot-controlled pressure regulator for medium and high pressure applications.

Reflux 819 is normally a fail to close regulator and specifically will close under the following conditions:

• Breakage of main diaphragm
• Lack of feeding to the pilot loop

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

The Reflux 819 is modular in design and allows retrofitting of a monitor PM/819, slam shut valve, and/or silencer in the same body. The Reflux 819 regulator is truly a “top entry design” which allows for easy maintenance and retrofitting options in the field. The unique dynamic balancing system ensures an outstanding turn-down ratio combined with an extremely accurate outlet pressure control.
