The Bosch Rexroth 4WRPH6CB25P-2X/G24Z4/M (0811404172) is a high-response directional control valve designed for advanced electro-hydraulic applications. This direct operated valve boasts servo quality performance with a precise control spool and sleeve, ensuring reliable and accurate operation. A notable feature of this model is its single-sided actuation which defaults to a 4/4 fail-safe position when deactivated, providing an added layer of operational safety. The valve is equipped with a control solenoid that includes electrical position feedback, coupled with electronics for the position transducer (Lvdt DC/DC), facilitating precise monitoring and adjustment of the spool position. This level of control is particularly beneficial in production and test systems where exact hydraulic movements are critical. Designed for subplate mounting, the Bosch 4WRPH6CB25P-2X/G24Z4/M conforms to the ISO 4401 porting pattern standard, ensuring compatibility with a wide range of hydraulic systems and simplifying installation. Its robust construction and high-quality components make it suitable for demanding applications that require quick response times and high precision.
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.
