The Bosch Rexroth Z2S22B2-5X (R900437818) is a high-quality isolator valve designed for efficient and reliable hydraulic control in various applications. This sandwich plate valve is part of the ZS series and is engineered to ensure leakage-free blocking of one or two actuator ports, even during extended periods of inactivity. It allows for free flow in one direction (A to A or B to B) while securely blocking the flow in the opposite direction. The design includes a control spool that, when activated, opens a ball seat valve and lifts the poppet off its seat, permitting fluid to flow from B to B. The system is crafted to allow for safe closure of the ball seat valve by hydraulically unloading the control spool as illustrated in the provided circuit example. One notable feature of this model is its preopening function, which aids in damped decompression of pressurized liquid, thereby minimizing potential switching shocks. The two-stage setup with an increased control open ratio ensures that even low pilot pressures can be unloaded securely. The Z2S22B2-5X adheres to the ISO porting pattern and can be utilized in vertical stackings within hydraulic systems. It offers various cracking pressures and comes with a standard preopening feature. For ease of installation and maintenance, check valve installation sets are available individually. Moreover, special versions of this valve can be requested to meet specific requirements, making it a versatile solution for controlling hydraulic flow within an array of applications where precise fluid management is critical.
