The Bosch Rexroth 4WRPH6C3B25P-2X/G24Z4/M (0811404043) is a high-performance, direct operated high-response valve designed for precision control in electro-hydraulic systems. This valve features a control spool and sleeve that ensure servo quality operation, providing users with reliable and accurate performance. It is uniquely designed to be actuated on one side, and when deactivated, it automatically assumes a 4/4 fail-safe position to ensure system safety. Equipped with an advanced control solenoid that includes electrical position feedback, the Bosch 4WRPH6C3B25P-2X/G24Z4/M valve integrates seamlessly with electronics for the position transducer (Lvdt DC/DC), enhancing its responsiveness and control accuracy. This feature is particularly beneficial for applications requiring precise motion control such as in production lines and testing systems where consistent results are critical. The valve's robust design allows for subplate mounting and follows the porting pattern according to ISO 4401 standards, facilitating easy installation and compatibility with various hydraulic systems. Its specific construction makes it suitable for use in demanding electro-hydraulic controls found within production environments and test rigs where reliability and precision are of utmost importance. The combination of high-quality materials, precise engineering, and advanced electronic integration makes this Bosch valve an essential component for sophisticated hydraulic applications.
Valves of type 4WRPH6 are direct operated high-response valve in servo quality with electric position feedback. The valves are actuated on one side and in their deactivated condition take a 4/4 fail-safe position. They are suitable for electro-hydraulic controls in production and test systems.
