DC1621M 微小流量調節閥                                                                                         DC1621M Micro-flow control valve

DC1621M系列微小流量調節閥閥芯部分采用針型或扁平式閥芯結構，最小可控Cv可達0.001，閥座直徑最小可達2mm確保精確控制。微小流量調節閥采用單座結構，高壓差時采用多級降壓結構，有效防止氣蝕；閥芯整體采用硬質合金，表面硬度可達HRC44~60，特殊密封副結構，泄漏等級可達零泄漏。

The DC1621M series micro flow control valve spool part adopts needle type or flat valve core structure, the minimum controllable Cv can reach 0.001, and the seat diameter can be as small as 2mm to ensure precise control. The micro flow regulating valve adopts single-seat structure. When the high pressure difference is used, the multi-stage pressure reducing structure is adopted to effectively prevent cavitation; the valve core adopts solid carbide, the surface hardness can reach HRC44~60, special sealing substructure, and the leakage level can reach zero. leakage.
