Specialityvalve is the prime Needle valve manufacturer in India. We supply to India, Brazil, Russia, United Kingdom and Italy. A needle valve is a type of valve that uses a small, tapered needle to control the flow of a fluid (liquid or gas). The needle is threaded and fits snugly into the valve body. By turning the valve handle, the needle is raised or lowered to precisely regulate the size of the opening between the needle and the seat. This controls the flow of fluid through the valve. Needle valves are commonly used in applications that require a small, precise flow adjustment, such as in laboratory equipment, fuel systems, and hydraulic circuits. They are also used in applications where it is necessary to control the flow of corrosive or abrasive fluids.
