  • Flow control valve and method for rebuilding a flow control valve
    Patent number: 8448919
    Abstract: A method for rebuilding a flow control valve, may be performed by first providing a flow control valve having a rotor positioned in a chamber of a valve body. The rotor has a valve stem. A top cover plate is mounted to the valve body above the rotor and has a first bore through which the valve stem protrudes. The top cover plate is removed so the rotor can be removed from the valve body. A seal is positioned on the top cover plate along the first bore so that when the rotor and top cover plate are placed in or on the valve body, the flow control valve is sealed at the interface between the top cover plate and the valve stem.
