Regulating the flow of a fluid by varying the size of the opening through which the chilled fluid passes, chilled water control valves are key components in fluid pipelines. In general, control valves consist of an electronic controller, which houses the modulating elements; a positioner, which determines the degree to which the valve opens; and an actuator, which initiates the mechanical movement of the controlling element. As a critical part of any fluid pipeline, the control valve helps regulate the fluid flow between the minimum requirement and the maximum installed capacity of the pipeline. These valves are often referred to as final control elements.
As systems expand and become more complex, the cause behind maintenance issues can vary – particularly with valves. During the course of valve management and maintenance, it’s likely that every technician will hear the familiar sounds of valve chatter.
Chattering is more than an auditory nuisance. Left unaddressed, chatter can and will lead to damaged valve components, reduced valve lifespan, costly downtime, and potential system-wide failure.
