Manifold Pressure Regulators HR 20 (Hauptdruckminderer)

Vulkan HR20  Effect is a manifold fin regulator for central gas supply systems that need a broader outlet-pressure window up to 20 bar. It is built for manifolds or direct bundle connection, with a brass body, ISO-based design, and versions for oxygen, inert gases, hydrogen, and compressed air.

 

Description

The HR20  Effect sits in the practical middle of the HR range: more outlet pressure headroom than HR10, but still compact enough for standard manifold installations. It is intended for users who need controlled gas distribution from bundles or central gas sources with inlet pressure up to 300 bar and outlet control up to 20 bar.

Gasetechnik24 positions the HR series as single-stage, ISO 7291 manifold regulators with adiabatic-compression-tested construction, inlet-pressure compensation, and safety gauges according to ISO 5171. That is the correct conversion angle for your page: stable pressure delivery, not generic catalog filler.
