The Four-Way Mixing Valve Training Unit "TEV4V" allows to demonstrate the function of a four-way mixing valve in a hot water heating system.
The Four-Way Mixing Valve Training Unit, "TEV4V", allows to demonstrate the function of a four-way mixing valve in a hot water heating system. The four-way mixing valve in the heating system regulates the circulation and feed flow temperatures of the water flowing in the heating system and the boiler return flow temperature.
The unit includes a four-way mixing valve, a boiler water circuit, a return heating system water circuit, a circulating pump, several thermometers and flowmeters.
The boiler water line (hot water) and the return heating system water line (cold water) includes several bimetallic thermometers and flowmeters to visualize the water temperature and flow in the inlets and outlets of the four-way mixing valve.
A pump circulates the mixture water of the heating system circuit. The differential pressure across the system is limited using a differential pressure relief valve.
Several bleed valves (air vents) remove the air from water and are situated in different points of the circuits.
