The Bosch Rexroth 4WRZE10W6-50-7X/6EG24N9ETK31/F1D3M (R901006547) is a state-of-the-art industrial hydraulic valve designed for reliable control of oil flow direction in high-performance applications.

This valve features integrated electronics and operates on a 24 VDC supply voltage, ensuring precise actuation through its electrical connectivity with an analog command value range of 4-20 mA. The size 10 valve, denoted by the symbol W, is equipped with a spool valve that is pilot-operated, featuring internal pilot oil supply and return. It comes with a pressure reducing valve and supports a maximum pressure operation. The unit's construction includes concealed manual override and auxiliary actuation, providing additional control in various operational scenarios. The spool symbol W indicates the specific flow path configuration of the valve. Designed for subplate mounting, it follows the connection diagram standards of NFPA T3.5.1 R2-2002 D03 and ISO 4401 size CETOP 05. With its high nominal flow capacity, this Bosch Rexroth hydraulic valve is capable of handling significant fluid dynamics, making it suitable for complex hydraulic systems requiring precise control. The model has multiple ports for versatile connection options and features NBR seals that ensure durability against typical hydraulic fluids like HL, HLP, HLPD, HVLP, HVLPD, and HFC. The WRZE series valves are known for their pilot-operated proportional directional control capabilities. They include proportional solenoids that proportionally move the main control spool according to the electric input signal, allowing for smooth and progressive flow characteristics during operation. This particular model is spring-centered with an optional manual override feature which must be used cautiously to prevent accidental machine movements due to uncontrolled activation. Users should also be aware that internal leakage may increase over the lifecycle of the valve due to its design principle.

Pilot-operated proportional directional valves type 4WRZ(E)… and 5WRZ(E).52…

Valves of type 4WRZ(E)... are pilot-operated 4-directional valves that are actuated by means of proportional solenoids. Their function is to control the flow direction and size.

Valves of type 5WRZ(E)... are equipped with an additional port "R" (only NG52).

Set-up:

The valve basically consists of:

Pilot control valve (9) with proportional solenoids (5 and 6)

Main valve (10) with main control spool (11) and centering spring (12)

Function:

With de-energized solenoids (5, 6), the main control spool (11) is held in the central position by means of the centering spring (12)

The main control spool (11) is controlled by the pilot control valve (9); the main control spool is proportionally moved, e.g. by actuating solenoid "b" (6)

→ The control spool (2) is moved to the right, pilot oil enters the pressure chamber (13) via the pilot control valve (9) and deflects the main control spool (11) proportionally to the electric input signal

→ Connection from P to A and B to T via orifice-type cross-sections with progressive flow characteristics

Pilot oil supply to the pilot control valve internally via port P or externally via port X

Switching off the solenoid (6)

→ The control spool (2) and main control spool (11) are moved back into the central position

Depending on the spool position, flow occurs from P to A and B to T or P to B and A to T (R)

An optional manual override (14 and 15) can be used to move the control spool (2) without solenoid energization.

Notice:

Accidental activation of the manual override may lead to uncontrolled machine movements!

Notice:

Due to the design principle, internal leakage which may increase over the life cycle is inherent to the valves.
