The Bosch Rexroth 4WRE6E16-2X/G24K4/V (R900954092) is a state-of-the-art industrial hydraulic valve that offers reliable and precise control over the direction and flow of oil in hydraulic systems. This direct-actuated spool valve, featuring external position feedback, is known for its high accuracy due to the internal piston position feedback mechanism. With a spool symbol E, it is designed for high-performance applications requiring exacting control.
This valve can manage a maximum pressure with an electrical connection described as a connector pole PE according to EN standards. It boasts integrated electronics for ease of use and has an electrical actuation type with external electronics, ensuring compatibility with various systems. The 4WRE6E16-2X/G24K4/V can accommodate a maximum flow and is suitable for subplate mounting with a connection diagram conforming to NFPA T.. R D SizeCETOP D and ISO standards.
It operates on a supply voltage of VDC, offering flexibility in terms of power sources. The valve's design includes several ports for comprehensive connectivity options and supports multiple types of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, HFDR. Seals made from FKM ensure durability and resistance against harsh fluids.
The Bosch Rexroth 4WRE6E16-2X/G24K4/V is built to deliver exceptional performance in controlling oil flow direction with precision. It is ideal for applications where accurate hydraulic responses are critical. Its robust construction and advanced features make it suitable for demanding industrial environments where reliability and efficiency are paramount.

Size 6, symbol E, external amplifier, 24 V DC
Industrial hydraulic valve in a high performance range. Reliable control of the direction of the oil flow according to hydraulic symbol. High accuracy thanks to internal piston position feedback
Unpacked Weight: 2.1 kg
Direct operated proportional directional valve with electrical position feedback and external electronics Control of flow direction and size Operation by means of proportional solenoids with central thread and detachable coil For subplate mounting: Porting pattern according to ISO 4401 Spring-centered control spool
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.
