Manifold Pressure Regulators HR 40 (Hauptdruckminderer)

Vulkan HR40  Effect is a higher-capacity manifold regulator for applications that need more flow and outlet pressure headroom. With up to 40 bar outlet pressure, robust brass construction, and HR-series manifold design, it fits serious central gas supply duties rather than light distribution tasks.

 

Description

The HR40  Effect is the step-up model for users who need materially more capacity than HR10 or HR20. With a maximum flow of 290 Nm³/h, outlet pressure range of 15–40 bar, and the same manifold-ready architecture, it is suited to central gas systems where pressure drop, reserve, and regulator stability are commercial issues rather than theoretical ones.

Competitor descriptions emphasize the same core sales logic across the HR family: single-stage design, ISO 7291 compliance positioning, adiabatic-compression-tested construction, inlet-pressure compensation, and safety gauges according to ISO 5171. That is the message that sells this model correctly.
