  Parker Needle Valves 
  NS系列针阀 Needle Valve, Subplate Mounted – NS Series 
           派克的NS系列针型阀为液压应用提供了很好的速度控制和关闭功能,无需进行自由回流检查。
Parker's NS series needle valve provides excellent speed control and shutoff for hydraulic applications where a free reverse-flow check is not needed.  
            
            
            
           派克的NS系列针型阀可以在低流量情况下调节旋钮前三圈进行微调,旋转三圈可以实现全开流量和常规的精密节流。
Parker's NS series needle valve allows fine tuning at low flow with the first three turns of the adjusting knob, with full-open flow plus conventional precision throttling with the final three turns of the knob.
