BUCHER电磁阀WECDK系列介绍
WEVDK系列……6 高性能带有内置供油阀芯的阀门采用内导式操控，并采用随动阀芯原理。主要阀体由铸铁体、以弹簧为中心的随动阀芯组件以及带压力密封芯管和套入式线圈的湿式电枢式电磁铁组成。这些阀门即使在极端工作条件下也能提供可靠的性能，例如高流量、高工作压力、电压下降、长时间不切换、液体温度大幅等。
高效的阀芯驱动方式结合了直动阀和两级电磁阀的优点，又避免了各自的缺点。主阀芯由电磁铁的作用和阀内部的P⇒T（压力-温度）压力差共同偏移。压力差越大，偏移力也越大。阀芯同样通过P⇒T压力差作用，用强大中心弹簧的方式返回到中位位置。如果流量极低或出现开路状态，导致P⇒T压力差消失时，阀芯的驱动机制将回归到普通的电磁铁/中心弹簧相结合的方案。
所有阀门标配手动超控装置，即使在管道压力较高的情况下，核心管中压力反向时，也能操作。
Series WEVDK ...--6 high Performance spool valves are internally piloted and use the follower spool principe. The main valve components are a cast body, a spring--centered follower spool assembly and wet armature Solenoids with pressure--tight core tube and slip--on coil. These valves provide reliable service even under the severest operating conditions such as very high flow rates, high operating pressures, supply voltage drops, long periods without switching, large and sudden changes in fluid temperature etc. The highly effective spool actuation method combines the advantages of direct acting and two--stage solenoid valves, without incurring the well known disadvantages of either type. The main spool is offset by both the solenoid force and the P ⇒ T *) pressure difference inside the valve. The greater the P ⇒ T pressure difference, the greater the offsetting force. The spool is returned to the mid--position in the same way, using the P ⇒ T pressure difference and without the need for the usual heavy centering springs. If very low flow rates, or an open circuit condition, result in there being no P ⇒ T pressure difference, then the spool actuaction reverts to the normal solenoid / centering spring arrangement. The manual over--ride, which is fitted as standard equipment to all valves, can be operated even when high tank line back--pressures exist in the core tube.
