ABSTRACT:
A system to flush the valve chamber of a valve (10) which is mounted in a flowline (12) by passing a cleaning fluid through the valve chamber when the valve is moved between open and closed positions. An actuator (38) operates a pair of flush valves (26, 32) which are connected to the valve body (14) for controlling the flow of the flushing fluid through the valve body. A flush control system is operated by movement of the flowline valve between the open and closed positions. The flush control system is connected to the actuator and operated when the flowline valve is moved from the open position to the closed position. The flush control system causes an operating fluid to be applied to the flush valve actuator so that the flush valves are opened to pass the flush or cleaning fluid through the valve chamber and then after a period of time again sequence the valve actuator to close the flush valves and terminate the cleaning of the valve chamber.
