Needle Valve
Needle Valve
A needle valve is a type of valve used to precisely control the flow of fluid, typically in low-flow applications. Its key feature is a small, tapered needle-like plunger that fits into a corresponding seat, which allows for very fine adjustments to the flow rate. Needle valves are commonly used in industries like oil and gas, chemical processing, and in laboratory settings where precise flow control is essential.
Key Components:
- Needle-shaped Plunger: The thin, needle-like plunger allows for fine control by gradually increasing or decreasing the flow area as it moves in and out of the valve seat.
- Valve Body: Usually made from corrosion-resistant materials like stainless steel or brass, depending on the application.
- Seat: The opening where the needle fits, controlling the flow of the fluid.
