The Bosch Rexroth Z2S10-1-3X/SO73 (R900706405) is an advanced isolator valve designed for the precise control of hydraulic systems. This releasable check valve, which comes in a sandwich plate design, is engineered to enable leak-free blocking of one or two actuator ports, even during extended periods of inactivity. It allows free flow from A to A or B to B and blocks flow in the opposite direction. The valve’s operation involves a control spool that moves to open the ball seat valve and displace the poppet from its seat, allowing fluid to flow freely. This model is equipped with preopening functionality that aids in the damped decompression of pressurized liquid, thereby preventing potential switching shocks and ensuring smoother operation. The two-stage setup with an increased control open ratio ensures that even low pilot pressures can be securely unloaded. The Z2S10-1-3X/SO73 is suitable for various applications due to its flexible design options which include different cracking pressures and the choice between standard preopening or an optional non-preopening configuration. To further enhance adaptability, check valve installation sets are available individually. Its corrosion-protected construction ensures longevity and reliable performance in challenging environments. Additionally, it adheres to international porting patterns set by ISO standards, ensuring compatibility with a wide range of hydraulic systems. Users should note that valves without preopening may experience sudden unloading of pressure volume leading to switching shocks and potential premature wear or noise in installed components. This model designates port T as TA and TB differently from some ISO conventions for clarity in its technical documentation.
