ABSTRACT:
A valve is provided with a throttle member that is capable of metering the flow between a bore channel of the valve and a port extending between the channel and an external location. The throttle member, or metering device, is a partial cylinder formed to include a plurality of deformations in its surface. The deformations can be slots that are shaped to receive a thread of a rotatable threaded member also attached to the valve body of the valve. Rotation of the threaded member can be arranged to cause the throttle member to rotation about the central axis of the channel and edges of the partial cylinder, which are circumferentially spaced apart from each other, can move into interfering relation between the port and the channel to partially block and meter flow therebetween.
