HL 105 Three-way mixing valve training panel
The trainer was designed for heating and plumbing trainees.
A three-way mixing valve in a heating system controls the circulation and feed flow temperature of the water flowing in the heating system. A pump circulates the water in the pipe system. The differential pressure across the pipe system is limited using a relief valve. Bimetallic thermometers indicate the temperatures at all relevant points in the heating circuit.
