2结构特点
●伺服阀直接装在液压缸上，容腔效应小，固有频率高。
●多种安装连接方式，使用方便。
●积木式结构，维护性好。
●采用组合密封和非金属支承，无内外漏油，摩擦力低、寿命长。
●可根据使用要求安装多种传感器。
●配有伺服阀转接板，可换装各种型号伺服阀。
●可设置可调式机械或电气保护装置。
●可设置多种形式的保护模块，模块。
可直接装在液压缸上，也可联接于系统管路中。
●可设置阻尼调节装置，调整动态性能。
●微磨擦、高频响的伺服缸采用静压支承形式。

features
● minor vacant effect and high natural frequency,since servo
valve is directly fixed on hydraulic cylinder.
● multiple installment forms accessible,easy to use.
● modular construction,easy to maintain.
● since the system has excellent combined sealing and non-metal
bearing,no internal or external oil leakage appear,friction forcegets lower,service life becomes longer.
● several kinds of sensors are available as re
● with adapter piate provided,various types of servo valve can
be replaced each other.
● mechanical or electric protective units adjustable.
● many forms of protective module can be set in,which can beeither
fixed on hydraulic cylinder or in system pipeline.
● the dynamic property is adjustable by arranging dampregulator.
●the slight-frictionuent servo cylinder adopts static
pressure bearing.
