Model N Needle Valve

A needle valve is a type of valve having a small port and a threaded, needle-shaped plunger. It allows precise regulation of flow, although it is generally only capable of relatively low flow rates. Pin valves are constructed with a small opening accompanied by a plunger that looks a great deal like a common sewing needle. The purpose of the needle valve is to create a means of controlling the flow of liquids or gases through the valve mechanism. It is possible to easily adjust the flow rate to any specific amount desired. Pin valves are usually used in flow metering applications, especially when a constant, calibrated, low flow rate must be maintained for some time, such as the idle fuel flow in a carburetor. A needle valve is also sometimes used in equipment that controls the temperature of water within a specific system. For example, some residential water heaters utilize this pin valve as a type of bleed valve that makes it possible to relieve pressure on the water flowing through the device. As with other applications, the needle valve makes it possible to control the flow of water through the heater, a factor that can also aid in minimizing the amount of energy needed to maintain an equitable supply of hot water.
