Welding needle valve

Product Overview:

Needle type instrument valve is a valve used for precision fluid control and is a key component in instrument piping systems. Its core feature is the use of a "needle shaped valve core" - the valve core is a sharp conical shape that can be accurately inserted into the valve seat, and fine control of fluid flow and pressure can be achieved through small opening adjustment. At the same time, it has excellent sealing performance and is suitable for scenarios with high precision and sealing requirements such as instrument measurement and industrial control systems.
