Parker N400S Needle Valve

Product Overview
The Parker N400S Needle Valve is a high-performance manual control valve designed for industrial applications requiring precise flow regulation and reliable sealing. Its unique two-step needle structure enables fine control: the first 3 turns of the adjusting knob provide precise micro-adjustment at low flow rates, while the next 3 turns fully open the valve and offer standard throttling adjustments, balancing accuracy and operational efficiency.
