This photo shows a new installation of a control actuator and piping.
Three way valve air handling unit.
Water cooled chiller piping diagram.
Many people will call all three way valves mixing valves.
Air handling unit includes factory installed reheat coil and check valves on the liquid and hot gas reheat lines.
The three way valve immediately above the chiller at the bottom of the diagram switches the system s mode of operation.
The control actuator is modulating and on a three way valve.
The described solutions from belimo will allow you to create an optimum room climate with minimum energy consumption.
Supply air temperature sensor is factory provided for field installation in the supply air ductwork.
There are two types of three way valves used in the hvac industry.
In this video you will learn the.
2 way characterised control valve m 3 way characterised control valve electronic pressure independent characte rised control valve epiv.
The valve will modulate depending on the supply air temperature of the air handling unit which provides air conditioned air to the space.
A schematic of a generic system is shown in figure 2.
2 way and 3 way control valves for ahu and fcu.
In order to prevent any misunderstanding due to terminology we will consider mixing valves to have two inlets and one outlet and diverting valves to have one inlet and two outlets.

The chilled water comes through a pipe to coils of ahu but before entering the coil there is a link taken out of this inlet line which is connected to the chilled out line the outlet line from coils of ahu for bypass purpose when temperature.
In the heating mode the return line from the room terminal units typically fan coils or unit ventilators bypasses the chiller and goes to a header that feeds the boilers.
