The Bosch Rexroth 4WRTE25E220L-4X/6EG24EK31/A5V (R978031519) is a sophisticated directional control valve designed for advanced hydraulic systems requiring precise control and reliability. This valve is part of the WRTE series, which are pilot-operated with electrical position feedback and integrated electronics (OBE). It offers the option for spool position monitoring to ensure accurate operation within complex applications. Constructed with a main housing, central control spool, and an integrated electronics unit, the 4WRTE25E220L-4X/6EG24EK31/A5V also features an inductive position transducer for accurate spool positioning. The pilot control valve is integral to the system, utilizing a control spool-socket unit with an inductive position transducer and pressure feedback for central positioning of the main stage control spool. This valve operates by controlling the main stage control spool via the pilot control valve, ensuring regulated positioning and precise fluid flow management. The proportional solenoids remain deenergized in a central position when not in use, maintained by centering springs and pressure feedback. A unique feature of this model is its capability to be used in safety-related two-channel applications up to category 3 PL d/e according to EN standards, functioning as a shut-off element for one channel. It also complies with secure start inhibitor requirements as per EN standards. For applications outside standard conditions that involve high humidity or significant temperature changes, an optional electronics protection membrane can be utilized to prevent condensate formation within the OBE housing. In case of supply voltage failure or cable breakage, the integrated electronics automatically deenergize the solenoid maintaining pressure control and centering of the main stage control spool via spring action. The Bosch Rexroth 4WRTE25E220L-4X/6EG24EK31/A5V offers flexibility in its application with various versions available regarding internal or external pilot oil supply and return configurations. This allows it to cater to different system designs effectively. Overall, this valve represents a reliable choice for those seeking precision in hydraulic system controls across various configurations while meeting stringent safety requirements.
