7.10. Water Flow Control Valve
The water flow control valve adjusts the valve position by collecting the cooling requirement, to control the water
flow through the heat exchanger coil. The higher the load is, the more water flow is required to flow through the
evaporator coil. The water flow control valve is composed of a regulator body, connector (some of the units may
not have a connector, please pay attention to the actual instance) and actuator. User should select the two way
valve or the three way valve depending on the application situation, as shown in Figure 7-4
