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).
Hydrogen Ready for NG-H2 blending.
The Reflux and Reval regulators are available in 1”-10” sizes in ANSI 150# rating in LCC steel body configurations with available outlet pressure ranges from 4”W.C -1073 psig. These regulator models feature a true “spring assist” and can be purchased in a true fail open (FO) or fail closed (FC) design. Due to the modular design this offering can be configured with patented noise silencer and optional high and low pressure slam shut module. Suitable applications would include power plant feeds, city gate stations, compressor fuel gas as well a district regulator settings. The Reval and Reflux offer superior durability for high pressure high volume pressure control applications where reliably and durability are paramount.
The Reflux and Reval regulator offering features:
- Top entry-four port modular design
- Balanced-high accuracy characterized pilot and plug design
- Class VI shut off
- 1000:1 turndown
- Optional silencer
- Optional slam shut module. (High and low pressure dual mode control)
