A needle valve is a type of valve having a diminutive port and a threaded, needle-shaped plunger. It allows specific regulation of flow, even though it is normally only competent of reasonably low flow rates. Needle valves are used to isolate the pressure gauge from the process or to stifle and to moisten the pressure pulses. Also the needle valve fitted with a tested connection enables simultaneous connection of a gauge to check the pressure in the pipe. Needle valves may also be used in vacuum systems, when a precise control of gas flow is required, at low pressure such as when filling gas-filled vacuum tubes, gas lasers and similar devices. An instrument needle valve uses a tapered pin to gradually open a space for fine control of flow. The flow can be controlled and regulated with the use of a spindle. A needle valve has a relatively small orifice with a long, tapered seat, and a needle-shaped plunger on the end of a screw, which exactly fits the seat. We are sincerely involved in manufacturing and supply of international quality standard Needle Valve. For fabricating these needle valves, we use top grade material, which is procured by us from the reliable sources. These high-performance needle valves can be availed from us according to client’s specifications and demands.
