Abstract: A valve stem for use in a fluid flow control valve having a valve body configured to receive a portion of the valve stem and to enable the valve stem to selectively rotate within the valve body between a fully-open position, where fluid is permitted to flow through the fluid flow control valve, and a fully-closed position, where fluid is prevented from flowing through the fluid flow control valve. The valve stem includes an elongate valve stem arm having a first end and a second end and a valve stem head integrally formed with and fixedly attached to the second end of the valve stem arm. The valve stem head includes a fluid inlet formed in the valve stem head, and a fluid outlet formed in the valve stem head, and a fluid passage that directs fluid from the fluid inlet, through the valve stem, and out of the fluid outlet.
