This shut-off valve finds its optimal application in industrial plants and laboratories where very accurate control of fluids is required. In fact, it is also used for regulating the flow, as well as for stopping it.
The needle valve is characterized by a plug shutter that is positioned in a conical seat that contains it. Since these are precision technical valves that can be used with aggressive chemical liquids or in contexts that require high hygiene, the stainless steel version is particularly recommended.
