 The 4-way pilot develops maximum shiftingorce both ways.
2. Memory spring available.
3. Balanced spool, immune to variations ofpressure, also provides high flow.
4. Short stroke with high flow.
5. Bonded spool with minimum friction, shiftingin a glass-like finished bore.
6. Pilot with balanced poppet, high flow, shortand consistent response times.
7. Wiping effect eliminates sticking.
换向阀主要由阀体、密封组件、凸轮、阀杆、手柄和阀盖等零部件组成(图1)。
阀门由手柄驱动，通过手柄带动阀杆与凸轮旋转，
凸轮具有定位驱动与锁定密封组件的开启与关闭功能。
阀瓣为碳钢板焊件，设有加强筋，即增加阀瓣强度又起导向作用，保证每组阀瓣间的同轴度。

阀瓣上镶嵌聚氨脂橡胶圈，该材料具有耐油、耐磨损、稳定、密封良好和使用寿命长的特点。
在凸轮的作用下，密封圈的球面与阀体密封面相接触产生挤压弹性变形，达到密封效果。
