The Bosch Rexroth 4WRZE25W9-220-7X/6EG24N9ETK31/F1M (R901418233) is a state-of-the-art industrial hydraulic valve designed for reliable control of oil flow direction, consistent with its spool symbol W. This high-performance valve features integrated electronics and operates on a 24 VDC supply voltage, ensuring precise actuation through electrical signals with an analog command value input of 4-20 mA. The valve is pilot-operated with an internal pilot oil supply and return, lacking a pressure reducing valve, which contributes to its streamlined functionality. The 4WRZE25W9-220-7X/6EG24N9ETK31/F1M valve boasts a concealed manual override and auxiliary actuation, enhancing its versatility in various operational scenarios. It has been designed for subplate mounting with connection compatibility to NFPA T3.5.1 R2 D03 and ISO CETOP R05 standards, offering ease of integration into existing systems. The nominal flow rate capacity of the valve ensures adequate handling of hydraulic fluid types such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. Equipped with NBR seals for durability against wear and potential fluid leakage, the valve maintains robustness in demanding environments. The unit comes with a connector pole PE according to EN standards for secure electrical connections. With its spring-centered control spool and multiple switching positions, the Bosch Rexroth proportional directional valve provides smooth and responsive control over hydraulic systems. This model's design includes a main valve with a spool and centering spring controlled by a pilot control valve actuated by proportional solenoids—allowing for precise adjustment of flow direction and size proportionally to the electric input signal. An optional auxiliary operating device can be utilized for manual control when solenoids are deenergized. Users should be aware that accidental activation of the manual override could result in unintended machine movements due to the inherent design principle that allows for internal leakage over the product's lifecycle.
