Inconel needle valves, having the unique properties, are mostly considered in chemical industries. Applications in which consistent and limited flow are required do require needle valves for their completion. Inconel Needle valves are used especially when a consistent, measured, low flow rate must be upheld for some time, such as the stagnant fuel flow in a carburettor. Needle valves are used in changing the direction of the flow.
Take to mind that the float valve of a carburettor (controls the fuel level within the carburettor) is not a needle valve, although it is described as one. It uses a blunt conical needle, but it seats against a square edged seat rather than a matching cone. The aim here is to obtain a well-defined set between 2 narrow joining surfaces, giving firm shutoff of the outflow from only a light float pressure. Since flow rates are less and many bends of the valve stem are required to fully open or close, needle valves are not used for simple shutoff applications.
The force advantage of the fine threaded stem is more since the opening is narrow, Needle valves are usually easy to shut off completely, with solely finger tight pressure. The spindle of a needle valve made from brass, when shutting off the flow can be easily damaged by extra turning force. Small simple needle valves are often used as bleed valves (hydraulic valves that combine one or more block/isolate valves,) in water heating applications. It is not easy to tell from examining the handle position and check whether the valve is open or closed, unlike a ball valve or valves with a rising stem.

An Inconel needle valve uses a tapered (reduce in thickness towards one end) pin to slowly open up space for subtle control of flow. The flow can be controlled and regulated with the use of a spindle (a slender rounded rod with tapered ends). An Inconel needle valve has a comparatively small opening with a long, tapered seat, and a needle-shaped plunger (part of a device or mechanism that works with a plunging) on the end of a screw, which exactly fits the seat. As soon as the screw is turned and the plunger retracts, flow is possible between the seat and the plunger, however, until the plunger is completely retracted, the fluid flow is significantly impeded. Since it takes many spins of the fine threaded screw to retract the plunger, precise regulation of the flow rate is possible. The virtue of the needle valve is from the vernier (a vernier scale is a device that lets the user measure more precisely than it could be done unaided when reading a circular measurement scale) effect of the ratio between the needle’s length and its diameter, or the difference in diameter between needle and seat. A long travel axially (control input) makes for a very small and significant change radially (affecting the resultant flow).Needle valves may also be used in vacuum cleaner systems, when a specific control of gas flow is required, at low pressure, such as gas filled vacuum tubes, gas lasers and similar devices.
