HL 113 Losses in Valves and Fittings Training Panel
Education / GUNT Hamburg / Thermal Engineering and HVAC / Heating and Ventilation in Buildings /

Five different pipe sections with various types of valves and fittings are fitted to the panel. The pipe sections can be individually selected using ball valves.

  One pipe section with ball valve is made of transparent PVC so that the flow can be clearly observed. A battery-powered digital differential pressure manometer is supplied. The flow rate is adjusted using valves.

Learning Objectives / Experiments

- Pressure loss at valves and fittings
- Effect of the shape of the flow passage on the 
  pressure loss
- Effect of flow rate
- Determination of loss coefficients

- Measuring the pressure difference
- Comparison of experiment and calculation
