The FCV offers repeatable water temperature control by controlling the flow of water in a mold water cooling application. The FCV is an electronically actuated needle valve (only available in 1″ ports) that is proportional to a command signal based on needle position.
In this sketch, the temperature sensor senses the temperature in the casting and sends a signal to the PLC. The controller then adjusts the command signal to the FCV to either increase or decrease the water flow to achieve the desired temperature.
The FCV can work with most (non-volatile) liquids and gases. The FCV has a Cv of 19 and can handle pressures up to 250 PSI out.
