The Bosch Rexroth 4WRPH6XB12L-2X/G24Z4/M-842 (0811404166) is a high-response, direct operated hydraulic valve with exceptional servo quality, designed for use in electro-hydraulic control systems within production and test environments. This model features a control spool and sleeve that ensure precise operation, while its single-sided actuation and 4/4 fail-safe position guarantee safety and reliability when the valve is in the deactivated state. The unit is equipped with a control solenoid that provides electrical position feedback, which is critical for accurate control of hydraulic systems. Additionally, it incorporates electronics for the position transducer (Lvdt DC/DC), enhancing its responsiveness and functionality. The 4WRPH6XB12L-2X/G24Z4/M-842 valve is specifically engineered for subplate mounting and adheres to the porting pattern set by ISO 4401 standards. Its robust design and advanced features make it an ideal component for sophisticated electro-hydraulic applications where precision and dependability are paramount. Whether integrated into manufacturing processes or utilized within testing setups, this Bosch valve stands out as a critical element in achieving fine-tuned hydraulic control.
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.
