NeoR Pressure Regulator

Brand: Pietro Fiorentini
Request Information
Hydrogen Compatible Hydrogen Compatible

The NeoR is a double stage gas pressure regulator by Pietro Fiorentini. Designed to ensure continuous gas supply while maintaining a high level of safety with reduced emission. The NeoR is a service regulator without slam-shut device, incorporating a double token relief valve (IRV) with partial capacity. It is particularly suitable for low pressure natural gas distribution systems for commercial and residential users. It should be used with previously filtered non-corrosive gases including biomethane and RNG (Renewable Natural Gas). The NeoR is Hydrogen Ready for NG-H2 blending.

Features
  • Operates with low differential pressure
  • Overpressure protection without slam-shut or full capacity IRV
  • Two-stage single orifice regulator
  • Built-in thermal valve option
  • Built-in strainer
  • Suitable for outdoor installations
  • Biomethane (RNG) compatible and 20% Hydrogen blending compatible. Higher blending available on request
  • CSA 6.18
  • ANSI B109.4
