PARKER NS Series Needle Valve, Subplate Mounted针阀
NS系列针阀为不需要自由反向流量检查的液压应用提供了极好的速度控制和关闭功能。帕克的NS系列针阀允许在低流量时通过前三圈调节旋钮进行微调，全开放流量加上传统的精密节流与最后三圈的旋钮。Parker's NS series needle valve provides excellent speed control and shutoff for hydraulic applications where a free reverse-flow check is not needed.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.
