The Bosch Rexroth 4WRE6WA16-2X/G24K4/V (R900965434) is a high-performance direct operated proportional directional valve with electrical position feedback, designed for precise control of flow direction and size in hydraulic systems. This model is engineered for subplate mounting with a porting pattern that conforms to ISO standards, ensuring compatibility and ease of integration into various hydraulic circuits.
With its robust housing and control spool, the valve facilitates smooth operation under maximum operating pressures of up to 350 bar and can handle maximum flow rates of approximately 16 liters per minute. The spring-centered control spool is meticulously balanced by compression springs, which maintain the spool in its central position when solenoids are deenergized. Activation of one of the proportional solenoids shifts the control spool proportionally to the electrical input signal, allowing for precise modulation of hydraulic flows.
The valve features two solenoids with central threads and detachable coils that are actuated by external electronics. This setup ensures responsive and accurate adjustments to fluid dynamics within the system. The inclusion of a position transducer offers real-time feedback on the spool's location, contributing to the valve's overall reliability and performance.
It's important to note that this model should not be tampered with mechanically as it may lead to damage; specifically, adjustments to the PG fitting or adjustment nut are prohibited. Additionally, users must ensure that internal leakage is considered as it may increase over time due to the inherent design principle of these valves. To prevent issues related to tank line drainage, installation conditions may necessitate a preload valve with an approximate preload pressure of 5 bar.
In summary, the Bosch Rexroth 4WRE6WA16-2X/G24K4/V (R900965434) proportional directional valve stands out for its precision engineering, providing reliable and efficient control in demanding hydraulic applications.

Type 4WRE...-2X/...
The 4/2 and 4/3 proportional directional valves are designed as direct operated devices in plate design. Operation by means of proportional solenoids with central thread and detachable coil. The solenoids are controlled by external electronics.
Set-up:
The valve basically consists of:
Housing (1) with connection surface Control spool (2) with compression springs (3 and 4) and spring plates (5 and 6) Solenoids (7 and 8) with central thread Position transducer (9)Function:
With de-energized solenoids (7 and 8), central position of the control spool (2) due to compression springs (3 and 4) between the spring plates (5 and 6) Direct actuation of the control spool (2) by the control of one proportional solenoid, e. g. solenoid "b" (8) Control spool (2) is moved to the left in proportion to the electrical input signal Connection from P to A and B to T via orifice-type cross-sections with progressive flow characteristics Switching off of the solenoid (8) Control spool (2) is returned to the central position by the compression spring (3)In the de-energized state, the control spool (2) is held in a mechanical central position by the return spring of the solenoids. With control spool symbol "V", this position does not correspond to the hydraulic central position! When the electric valve control loop is closed, the control spool is positioned in the hydraulic central position.
Important notice:
The PG fitting (11) must not be opened. Mechanical adjustment of the adjustment nut located below is prohibited and damages the valve!
Valve with two spool positions: (Type 4WRE…A...)
The function of this valve version basically corresponds to the valve with three spool positions. The 2 spool position valve is, however, only equipped with solenoid “a” (7). Instead of the 2nd proportional solenoid, a plug screw (10) is installed.
Notice:
Due to the design principle, internal leakage which may increase over the life cycle is inherent to the valves.
Notice:
The tank line must not be allowed to run empty. With corresponding installation conditions, a preload valve (preload pressure approx. 2 bar) must be installed.
