A needle valve is a particular type of valve one which has an unusually small port and a needle-shaped plunger that moves up and down within the confines of the port. In this way it resembles a needle inside a syringe which is how it gets its name. The plunger can be moved up and down within the port allowing for more precise flow control.
2017-2-1 · Needle Control Valves A needle control valve is a variable control valve that is not pressure compensated. The fluid will come in and be forced to make two ninety degree turns and there is a needle in the valve in the way of the fluid. It basically creates a pressure differential in between the upstream and the downstream.
2015-11-19 · Uncategorized. Needle Valves How does it work This is a type of a valve that has a port and threaded needle-like plunger that allows smooth and accurate low of fluids .This valves operates with a narrowing pin which gradually opens a pathway for perfect fluid flow control. A spindle is used to control and adjust the fluid flow.
2019-7-20 · Needle valve . What is a needle valve Needle valve as a member of huge valve family has been playing a vital role at gradually and ultimately closing off the flow. Various needle valves are used to regulate the amount of substance released by force flow and direction. So they are indispensable parts of most industrial process.

For the needle valve to work the user will rotate the stem comfortably gripping the handle for ease of rotation. As the needle rotates the threaded sides turn and the needle is either lowered or raised out of the seat. Because of the threading the actual change in needle depth for every turn is extremely minimal.
