Abstract:
A control system for a fluid piping system, comprising:at least one flow valve having a flow valve fluid inlet and a flow valve fluid outlet; a control valve in fluid communication with the flow valve and configured to operate the flow valve by controlling the flow of fluid through the fluid piping system through the flow valve fluid inlet and out the flow valve fluid outlet; a flow valve actuator for requesting activation of the control valve for operation of the flow valve; and a central control unit adapted for receiving, processing, and transmitting data signals between the flow valve actuator and the control valve for operation of the flow valve such that the central control unit determines whether activation of the control valve based on an activation request from the flow valve actuator would exceed a predetermined allowable activation quantity within a first predetermined time period, prevents activation of the control valve for a second time period if activation of the control valve would exceed a predetermined allowable activation quantity within the first predetermined time period, and records any request for activation of the control valve received from the flow valve actuator during the second time period.
