Valve, Needle
This type of valve is a special case of a globe valve. The flow should (but does not always do so) come up under the needle (from the right) and then goes around the needle and out to the left. The flow pattern in most valves is set up so that when the valve is closed that the valve packing is on the low pressure side. This reduces the probability of leaks.
