简单介绍
原装供应HAWE换向阀,哈威换向阀量程选择
这种换向阀设计成单体安装，其特征为内泄漏平衡，因此，无须泄漏油口。
各种型号的阀相应适用于；
。直接管式连接或
。板式安装
换向阀均由控制元件（滑阀包括阀体）和已直接安装的操纵装置所组成。
阀件全由钢制成，这就使阀体能承受压力冲击，也不渗漏。

The inner hole of the valve body is honing with gold steel.
The hardened and grounded spool is polished / deburring.
These measures ensure that their roundness and precision geometry (the control edges are not worn or widened),
and proper sealing gaps ensure minimal leakage.
压力冲击造成的影响，在铸造阀体长时期使用之后有时能观察到，
表现在外表上形成并变迁的细微裂纹，特别是当运行于全额许用压力之下。
在本系列换向阀中，这种现象从一开头就可完全避免。阀体内孔用金钢珩磨。
Casting materials (molded castings of zinc and aluminum) are used only for pressure-free
parts such as operating mechanism housings, spring covers, and bottom plates.
It is also possible to provide a manual manipulator housing for ductile iron,
especially when used in harsh conditions and in series with valves.
淬硬和磨削过的阀芯经过抛光/去毛刺。
这些措施保证了其圆度和精度的几何形状（控制边不致磨损或变宽），恰当的密封间隙确保泄漏小。
铸造材料（锌和铝的模压铸件）只用于无压零部件，如操纵机构壳体，弹簧盖，底板等。
也可提供球墨铸铁做的手动操纵机构壳体，特别在恶劣工况下以及阀串联连接时使用。
概述
The impact of pressure shocks can sometimes be observed after a long period of use in the casting valve body,
A fine crack that forms and changes on the surface, especially when running under full allowable pressure.
In this series of directional control valve,
this phenomenon can be completely avoided from the beginning.
滑阀式换向阀通常用于液压油作介质的液压系统。
换向阀用于控制液流方向，从而控制执行机构（液压缸或液压马达）的运动方向。
Slip valve type valve is usually used for hydraulic oil as a hydraulic system.
The directional control valve is used to control the flow direction and control
he direction of movement of the actuator (hydraulic cylinder or hydraulic motor).
The directional control valve is designed as a single unit,
