- 液压操纵的直动式换向滑阀
- 两位阀有定位器供选择
- 板式连接
说明：
WH型换向阀是液动式换向滑阀，它控制液流的开启、换向和停止。该阀主要由阀体、一个或两个控制活塞、阀芯、一个或两个复位弹簧组成。
WH.../... 型：
当控制活塞无压力油时，阀芯靠复位弹簧保持在中位或初始位置。当压力油作用在控制活塞上时，活塞推动阀芯，使其由静止位置移到所要求位置，从而打开需要的流动截面。当压力油去除后，阀芯由复位弹簧推回到原始位置。
WH.../O... 型：
此类阀是一种无复位弹簧不带定位装置、带两个控制活塞的两位阀。无压力油作用时，阀芯的位置是不固定的。
WH.../OF... 型：
此类阀是一种带一个定位器、无复位弹簧、带二个控制活塞的二位阀。无压力油作用时，阀的两个位置都是固定的。
插装阻尼器：
由于工作条件限制，切换过程中可能出现阀的流量超过阀性能曲线上规定的流量，这时需要采用阻尼器。它安装在阀的P腔或油路中。
