Product Category详细介绍
CN8系列偏心旋转控制阀在结构上,阀体、上阀盖为一体式结构, 阀体内腔为流线直通型,流路简单,对流体运动阻力小,压降损 失小,可减少对阀体及阀内组件的冲刷。阀芯的回转中心不与旋 转轴同心,可减少阀座磨损,延长使用寿命,阀芯上到有导流板, 有利于流体动态平衡,具有优良的稳定性。其次,还有流量大、 可调范围广等优点。特别适用于含淤浆的工艺系统控制。
CN8 series eccentric rotating control valves plug's geometric center deviates with rotation axis, which can reduce the seat abrasion and extend the lifetime of the product. The flow guiding wing at the plug's back is good for stabilize fluid flow, so it has excellent stability. In addition, it has large flow capacity and wide range ability. It is especially suitable for the control of those slurry fluids susceptible to clogging. CN8 series are characterized by compact structure, large output torque, effective handle and long lifetime.
-采用一体式、直通型流道的阀体结构,流通能力强,可调比大,流道简单,防堵能力强;
-加长型阀座设计,进口流路得到充分保护,免于冲刷,提高了阀门的使用寿命;
