三位四通、二位四通或二位三通型式。
驱动方式可采用内部或外部先导控制：WEH型为电液驱动，WH型为液压驱动。
用于底板安装。
油口布置符合ISO 4401。
可采用弹簧或压力对中，以及弹簧端位或液压端位。
可选湿式直流或交流电磁铁。
电气连接可采用独立连接或集中连接。
可选版本包括手动应急操作、切换时间调节、主阀P通道预紧阀，以及行程设定和／或阀芯位置监测。
WEH型阀为电液驱动的滑阀换向阀，控制液流启动、停止及方向。主要由带阀体（1）的主阀、主阀芯（2）、一个或两个复位弹簧（3.1）、（3.2），以及带一个或两个电磁铁“a”（5.1）和／或“b”（5.2）的先导阀（4）组成。
为确保正常工作，必须正确排出液压系统内的空气。
对于三位阀，主阀中的主阀芯（2）由两根弹簧保持在零位或初始位置；对于二位阀，则由加压和弹簧共同保持。在初始位置，两个弹簧腔（6）和（8）经先导控制阀（4）无压接回油箱。先导油经控制油路（7）供给先导控制阀，可采用内部供油或外部供油（外部通过 X 口）。操纵先导控制阀时，例如给电磁铁“a”通电，先导阀芯（10）向左移动，使弹簧腔（8）承受先导压力，弹簧腔（6）则仍处于无压状态。先导压力作用于主阀芯（2）的左侧，克服弹簧（3.1）的作用使其移动，从而在主阀中接通 P 至 B、A 至 T。
电磁铁断电后，先导阀芯（10）返回初始位置，脉冲阀芯除外。弹簧腔（8）卸压至油箱。先导回油可采用内部方式（经 T 通道）或外部方式（经 Y 通道）。可选的手动应急操作装置（9）允许在电磁铁未通电时移动先导阀芯（10）。
注意：
即使阀垂直安装，在无先导压力时，弹簧腔（6）、（8）内的复位弹簧（3.1）、（3.2）也可使主阀芯（2）保持中位。
由于结构原理所限，阀存在固有的内泄漏，且内泄漏可能在使用周期内增加。
WH型阀是液压驱动的滑阀换向阀，控制液流启动、停止及方向。主要由阀体（1）、主阀芯（2）、弹簧复位或对中版本中的一个或两个复位弹簧（3.1）、（3.2），以及转接板（11）组成。
主阀芯（2）由压力直接驱动，通过弹簧或压力保持零位或初始位置。先导油供油与回油均为外部方式，参见“先导油供油”。
阀芯采用弹簧对中的三位四通换向阀
该版本中，两个复位弹簧（3.1）、（3.2）使主阀芯（2）保持零位。通过转接板（11），弹簧腔（6）与Y口相通，弹簧腔（8）与X口相通。
向主阀芯（2）两个端面之一施加先导压力时，阀芯移向相应阀位，接通所需油口。当受压端面卸压时，对侧弹簧使阀芯返回零位或初始位置。
主阀芯采用压力对中的三位四通换向阀
主阀中的主阀芯（2）通过两端面受压保持零位。一个对中衬套（12）抵靠阀体并确定阀芯位置。释放一个端面的压力后，主阀芯（2）移向相应阀位。
已卸压的阀芯端面将回流先导油经先导控制阀排至外部Y通道。
注意：
该版本的弹簧（3.1）、（3.2）不具有复位功能，仅在无压且水平安装时，使主阀芯（2）保持中位。

| 4) | Pilot oil supply internal: |
| 5) | For symbols C, F, G, H, P, T, V, Z, an internal pilot oil supply is only possible if the flow from P to T in the central position (for 3-spool position valve) or while crossing the central position (for 2-spool position valve) is so large that the pressure differential of P to T reaches a value of at least 109 psi. For a pressure differential below 109 psi, a check valve with a cracking pressure of 109 psi is to be provided in the return line to the tank. An external pilot oil supply Y is required. |
| 6) | Pilot oil supply X internal is only possible for a pressure at P of minimum 65 psi. For symbols with negative overlap F, G, H, P, T, V, (S only NG16), a certain flow from P to T in the central position is necessary for this purpose (see "characteristic curves"). For symbols C, HC, Z, HZ, a flow of >42.3 US gpm is required during passing over the central position for NG16, for NG22, 25 and 32 a flow of >47.6 US gpm. If the required flows are not reached, a preload valve has to be used. When using a preload valve, the pressure differential of the preload valve of the corresponding size (see "Project planning information") is to be added to the corresponding pressure differential in case of direction of flow P ("see characteristic curves"). |

注意事项：
切换时间 = 先导控制阀触点接通至主阀控制边开始开启，且控制阀芯行程变化达到 95 % 所需的时间
切换时间按 ISO 6403 测得，使用 HLP46，ϑoil = 104 °F ±9 °F)。油温不同时，结果可能变化。
切换时间使用直流电磁铁测得。使用交流电磁铁时，约缩短 20 ms。
电磁铁断电时会产生电压峰值，可采用适当的二极管减小该峰值。
使用 "D3" 减压阀时，切换时间约增加 30 ms。
切换时间是在理想条件下测得的，根据具体应用条件，在系统中可能有所不同。
