Specifications pilot pressure regulator Harnoreg

Pilot regulator type Harnoreg

The Harnoreg is not a stand-alone gas pressure regulator, but a pilot pressure regulator that is mounted on an Axial Flow Valve (AFV). Due to its unique construction, the AFV offers many options that are important for optimum control. The AFV is easy to maintain and more compact than any other controller. The AFV is suitable for pressure regulation as delivery regulator (AR), distribution regulator (DR), quantity regulation, pressure relief and pressure limiting safety, using the correct regulating system. The AFV can be used as an active regulator, but also in combination with a second AFV as monitor-active or 2-stage setting. The Harnoreg pilot pressure regulator has been developed specifically for low outlet pressures.


Harnoreg type AR is suitable for a delivery station and has a pressure gauge of 0-2.5 mm and a restriction of 1.5 mm.

Harnoreg type DR is suitable for a distribution station and has a pressure gauge of 0-1.6 mm and a restriction of 0.8 mm.
