Needle Valve
African Valve is a reliable Needle Valve Manufacturer in Libya, providing precision-engineered valves designed for accurate flow regulation in instrumentation and low-flow piping systems. Known for their fine-threaded stems and narrow needle-shaped plungers, these valves allow precise control of flow rates in high-pressure and high-temperature applications.
Function & Working
Needle valves function by turning a threaded stem which moves a tapered needle into or out of a small orifice. This setup enables extremely fine control over flow rate and allows the operator to make gradual adjustments, ideal for throttling applications and maintaining consistent process parameters in sensitive systems.
