特殊系列調(diào)節(jié)閥 Special series regulating valve
DC1621M 微小流量調(diào)節(jié)閥 DC1621M Micro-flow control valve
DC1621M系列微小流量調(diào)節(jié)閥閥芯部分采用針型或扁平式閥芯結(jié)構(gòu)，最小可控Cv可達(dá)0.001，閥座直徑最小可達(dá)2mm確保精確控制。微小流量調(diào)節(jié)閥采用單座結(jié)構(gòu)，高壓差時(shí)采用多級(jí)降壓結(jié)構(gòu)，有效防止氣蝕；閥芯整體采用硬質(zhì)合金，表面硬度可達(dá)HRC44~60，特殊密封副結(jié)構(gòu)，泄漏等級(jí)可達(dá)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.
