The Bosch Rexroth 4WRA6E00-2X/G24N9K4/V-640 (R900940577) is a high-performance proportional directional valve designed for direct operation and subplate mounting. This valve is engineered to precisely control the direction and magnitude of flow within hydraulic systems. It operates using proportional solenoids with a central thread and detachable coil, which require external control electronics for operation. The 4WRA6E00-2X/G24N9K4/V-640 valve consists of a housing with a connection surface, a control spool balanced by compression springs, and solenoids that facilitate direct control over the spool. When the solenoids are deenergized, the control spool remains in its central position due to the compression springs. Upon energization of a proportional solenoid, the spool moves proportionally to the electric input signal, allowing fluid connection from P to A and B to T through orifice-type cross-sections with progressive flow characteristics. This model features two spool positions (type WRA...A...) and operates with only one solenoid (solenoid 'a'), using either a plug screw or cover for where the second solenoid would be situated depending on the size (NG6 or NG10). The design ensures that even when switched off, the spring returns the spool to its central position. It is important to note that this valve must not operate with an empty tank line; installation conditions may necessitate a preload valve with approximately bar preload pressure. The Bosch Rexroth 4WRA6E00-2X/G24N9K4/V-640 is optimized for applications requiring precise hydraulic flow management without electrical position feedback, ensuring reliable performance in various hydraulic systems. It adheres to ISO standards for porting patterns, making it compatible with widespread industry practices.
