***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth 4WRZ16E150-7X/6EG24N9EK4/M (R900977992) is a high-performance, pilot-operated proportional directional valve designed for controlling the flow direction and size in hydraulic systems. This model is part of the WRZE series, characterized by its ability to actuate via proportional solenoids. The valve features an additional port R for NG size configurations and is equipped with a main control spool that is held in a central position by a centering spring when solenoids are deenergized.
The operation of this valve involves the pilot control valve, which proportionally moves the main control spool in response to an electric input signal. This action allows pilot oil to enter the pressure chamber and deflect the main control spool accordingly, enabling progressive flow characteristics through orifice-type cross-sections. The WRZE series valves can be supplied with pilot oil either internally via port P or externally via port X.
Designed for subplate mounting with a porting pattern according to ISO standards, this Bosch Rexroth valve supports maximum operating pressures of up to bar and can handle maximum flow rates of l/min. It comes in various sizes including , , , , and belongs to component series X. An optional auxiliary operating device is available for manual override, which should be used cautiously as accidental activation may cause unintended machine movements.
Furthermore, users should be aware that due to its design principle, internal leakage may occur and potentially increase over the lifespan of the valve. The 4WRZ16E150-7X/6EG24N9EK4/M offers reliable performance for controlling fluid dynamics in hydraulic systems without integrated electronics OBE (On Board Electronics), ensuring precise operation through its spring-centered control spool mechanism.

Pilot-operated 2-stage proportional directional valve without integrated electronics (OBE) Control of the direction and magnitude of a flow Operation by means of proportional solenoids with central thread and detachable coil For subplate mounting: Porting pattern according to ISO 4401 Optional auxiliary operating device Spring-centered control spool
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.
