A needle valve is a type of valve with 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.
The brass needle valves are designed for accurate control of flow rates for fluids and gases and provides a positive leak tight shut-off. With a wide variety of port sizes from G 1/8″ up to G 2″, pressure ratings up to 100 bar and temperature ranging from -30°C to 110°C, the needle valves offer a solution for a wide range of applications.
Advantages：
(1)Smooth and accurate flow control
(2)Reliable leak tight shut off
(3)Very compact design
(4)Suitable for a wide variety of media and applications
Disadvantages:
(1)Only clean fluids or gases
(2)Relatively high pressure loss compared with e.g. ball valves
Application
Suitable for Air, Water and Petroleum based products. Needle valves are commonly used to control flow and protect delicate gauges from damage caused by sudden pressure surges of liquids and gases. They’re ideal for systems using lighter and less viscous materials with low flow rates.
