Single-tube circuit system for heating plants

摘要

The single-tube circuit system has outward (3) and return (2) flow through a tube (5) in the circuit from the supply source (1), with or without through flow reduction. Heat regulation is controlled at the point of use (7) via a three-way valve (6), manually or automatically. Through flow regulation in the flow direction between output and return of the valve can be achieved by the installation of a manually-controlled or automatic reducer (9).
