Socket-weld needle valve

Overview: 

The needle-type instrument valve is a type of valve used for precise fluid control and is a key component in the instrument piping system. Its core feature is the use of a "needle valve core" - the valve core is in the shape of a sharp conical body, which can be precisely inserted into the valve seat. Through a small opening, it can achieve precise control of fluid flow and pressure, and at the same time, it has excellent sealing performance, suitable for scenarios with high requirements for precision and sealing, such as instrument measurement and industrial control systems.
