The Bosch Rexroth 4WRPH10C3B50L-2X/G24K0/M (R901222250) is a high-response directional valve that offers exceptional performance and reliability for demanding applications. This direct-operated valve is designed with a control spool and sleeve in servo quality, ensuring precise control and responsiveness. Its robust construction makes it suitable for challenging environments, particularly in the wood industry or in settings where aggravated environmental conditions are present. The model features an electric position feedback mechanism that allows for accurate monitoring of the valve's position, contributing to the system's overall efficiency and safety. The 4WRPH10C3B50L-2X/G24K0/M operates on one side and defaults to a failsafe position when deactivated, which enhances the safety aspect of machinery operation. Designed for subplate mounting, this valve adheres to the ISO porting pattern standards, ensuring compatibility with a wide range of systems. It boasts an impressive maximum operating pressure of up to 315 bar and can handle a maximum flow of up to 750 liters per minute while maintaining a nominal flow rate. The unit's ruggedized design features a central connector for simplified electrical connections, further emphasizing its suitability for industrial applications where durability is key. With its combination of high-response operation, robust design, and failsafe functionality, the Bosch Rexroth 4WRPH10C3B50L-2X/G24K0/M (R901222250) is engineered to meet the stringent requirements of modern hydraulic systems where precision and reliability are paramount.
Valves of type 4WRPH-750 are direct operated high-response valve in servo quality with electric position feedback and robust design. The valves are actuated on one side and in their deactivated condition take a 4/4 fail-safe position. They are suitable for use in the wood industry and in installations with aggravated environmental conditions
