Needle Valves for Accurate High-Pressure Flow Control

Needle valves are precision devices designed to provide accurate control of fluid flow in high pressure systems. They allow for fine adjustments of flow rates, making them ideal for flow metering and applications that require precise control. Often used alongside a pressure gauge, needle valves ensure stable and reliable performance, allowing operators to regulate fluid flow with exceptional accuracy.

A needle valve is a high-precision valve used for accurate regulation of very small flow rates. Its core design features a slender tapered valve core (needle-shaped) that fits precisely with the valve seat to achieve fine fluid control. It is mainly applied in laboratory instruments, hydraulic systems, gas regulation, and high-precision industrial processes. Domestic design standards include JB/T 7747, or it can be designed according to ASME B16.34 or GB/T 12224.
