SHNV Series High Pressure Needle Valve – S-LOK Korea

What is a Needle Valve?

A needle valve is a type of flow control valve with a small orifice and a long, tapered needle-shaped stem used to precisely regulate fluid flow in gas, steam, oil, and liquid systems.

It is commonly used in applications requiring:

• Low flow rate control
• High pressure resistance
• High precision adjustment
