哈威SF，SD，SK，SU型调速阀的 zui大压力Pmax＝315bar zui大流量Qmax＝0.3至130 l/min。 哈威SF，SD，SK，SU型调速阀可作为二通和三通调速阀交货。哈威调速阀可无级调节液压系统流量，而SU型调速阀可用于两档恒定的流量的调节。流量系数不取决于液压系统压力和介质粘度，并被稳定地保持在其zui小的偏差范围内。通过集成其它机能的阀（如溢流阀、卸荷阀或用外部Z口控制）可满足特殊要求。也可提供装有旁通单向阀和任意流通方向的桥式回路的二通调速阀。多种操作方式使此种调速阀更具有广泛的使用性。哈威HAWE流量控制阀 HAWE哈威调速阀

哈威SF/SD/SK/SU型调速阀，哈威流量阀东莞*，哈威SF/SD/SK/SU型流量控制阀型号说明：

The flow valves type SF, SD, SK and SU are available in 2 and 3-way versions.  They enable continuous adjustment of the oil flow settings in oil-hydraulic systems.  With the type SU, a choice can be made between two constant flows.  The flow rate is kept constant within a close tolerance regardless of the system  pressure and viscosity of the hydraulic oil.  Additional  functions （pressure-limiting valve and idle circulation valve  integrated in the valve or implemented externally via Z  port） enable  adjustment to specific requirements.  The 2-way flow  valves are available with bypass check valve and bridge circuit  for free selection of the flow direction.  The various actuation modes make these flow valves suitable for a broad range  of applications哈威HAWE流量控制阀 HAWE哈威调速阀
