在A、B或P通道中减压。
防腐蚀结构。

ZDR型阀是带二次回路限压功能的叠加板式直动减压阀，用于降低系统压力。

减压阀主要包括阀体（1）、控制阀芯（2）、压缩弹簧（3）、调节装置（4）以及可选单向阀。

通过调节装置（4）设定二次压力。

“A”版本。

阀在初始位置开启，液压油可由A➀无阻流向A➁。同时，A➁通道压力经控制管路（5）作用于压缩弹簧（3）对侧的活塞面积。压力超过弹簧（3）设定值时，控制阀芯（2）克服弹簧移至控制位置，使A➁通道压力保持设定值。

控制信号和先导油通过控制油路（5）从通道 A➁ 内部引入。

若执行器受到外力，导致通道 A➁ 中的压力继续升高，压力会推动控制阀芯（2）进一步克服压缩弹簧（3）的作用而移动。

由此，通道 A➁ 经控制阀芯（2）上的控制边（6）及阀体（1）与油箱（TB 通道）连通。足量液压油排入油箱，使压力不再继续升高。

弹簧腔（7）的泄漏油始终通过TA通道外部排出。

压力表接口（8）可用于检查阀的二次压力。

对于“A”型，可使用单向阀实现从通道 A➁ 至 A➀ 的自由回流。

“P”及“B”版本。

对于“P”型，在通道 P➀ 中减压。控制信号和先导油均由通道 P➀ 内部引入。

对于“B”型，在通道 P➀ 中减压，但先导油取自通道 B。若换向阀处于 P 至 A 的阀位，通道 B 的压力不得超过设定的二次压力，否则通道 A 中会发生减压。

注意：

若不配换向阀使用，则将 TA 和 TB 通道相互连接，例如在盖板中连通。

安装 NG 10 座阀式换向阀时，必须使用 HSZ10A078-3X/M00 型叠加板（物料号 R900537264）。

Important information on hydraulic fluids: For more information and data on the use of other hydraulicfluids, please refer to the data sheets above or contact us. There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature. Bio-degradable and flame-resistant – containing water: If components with galvanic zinc coating (e.g. version "J3" or "J5") or parts containing zinc are used, small amounts of dissolved zinc may get into the hydraulic system and cause accelerated aging of the hydraulic fluid. Zinc soap may form as a chemical reaction product, which may clog filters, nozzles and solenoid valves - particularly in connection with local heat input. Flame-resistant – containing water: Due to increased cavitation tendency with HFC hydraulic fluids, the life cycle of the component may be reduced by up to 30% as compared to the use with mineral oil HLP. In order to reduce the cavitation effect, it is recommended - if possible specific to the installation - to back up the return flow pressure in ports T to approx. 20% of the pressure differential at the component.
