ABSTRACT:
A control valve for regulating flow of fluids has an actuator located in a control chamber connected to a valve body. The valve body defines a flow passageway passing through an opening. A plug is associated with the actuator such that movement of the actuator from a retracted position towards an extended position displaces the plug towards the opening. The valve also includes a guide-and-seat insert which provides a valve seat interconnected with an attachment collar via a number of plug guides. When the plug is displaced by the actuator, the plug slides in contact with at least two of the plug guides. When the actuator moves to its extended position, the plug closes against the closure surface of the valve seat so as to block the passage of fluid from an inlet to an outlet of the valve.
