DC1621M 微小流量调节阀                                                                                         DC1621M Micro-flow control valve

DC1621M系列微小流量调节阀阀芯部分采用针型或扁平式阀芯结构，最小可控Cv可达0.001，阀座直径最小可达2mm确保精确控制。微小流量调节阀采用单座结构，高压差时采用多级降压结构，有效防止气蚀；阀芯整体采用硬质合金，表面硬度可达HRC44~60，特殊密封副结构，泄漏等级可达零泄漏。

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.
