***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 Z4WEH16E63-5X/6EW110N9ETK4/B10 (R901256925) is a high-performance directional spool valve, specifically designed for electrohydraulic actuation. This valve is adept at functioning as either a shutoff through the valve or a shutoff short-circuit through the valve, offering versatility in application. The design allows for free flow between P and T in every spool position, ensuring efficient operation.
The Z4WEH16E63-5X/6EW110N9ETK4/B10 conforms to the ISO porting pattern standard, facilitating its integration into various hydraulic systems. It offers the flexibility of using either wet-pin DC or AC solenoids, with the option to choose based on system requirements. Additionally, customers can request an optional auxiliary operating device with electrical connections tailored as individual connections; a central connection can also be provided upon request.
To enhance its functionality and adaptability to specific system needs, this model includes optional features such as switching time adjustment and stroke setting at the main spool. These options allow for precise control over the valve's performance characteristics. For monitoring purposes, it supports inductive position switch and proximity sensors which are contactless, thereby improving reliability and reducing wear.
The component series X of this model indicates its robustness with a maximum operating pressure of bar and an impressive maximum flow rate of l/min. These specifications denote that the Z4WEH16E63-5X/6EW110N9ETK4/B10 is suitable for high-pressure applications requiring significant fluid throughput.
In summary, Bosch Rexroth's Z4WEH16E63-5X/6EW110N9ETK4/B10 offers advanced control features in hydraulic systems where electrohydraulic actuation is necessary. Its compliance with industry standards and customizable options make it a flexible solution for controlling fluid flow efficiently and accurately within various operational contexts.

Notices!
Actuation of the manual override is only possible up to a tank pressure of approx. 50 bar. Avoid damage to the bore of the manual override! (Special tool for the operation, separate order, material no. R900024943). When the manual override is blocked, the actuation of the solenoid must be prevented!
The simultaneous actuation of the solenoids must be prevented!
Switching times (= Contacting at the pilot control valve until start of opening of the control edge in the main valve and change in the pressure value by 5 %)
Inductive position switch type QM: electrical connection
The electric connection is realized via a 4-pole mating connector (separate order) with connection thread M12 x 1.

The stroke of the main spool is limited by the stroke setting.
The piston stroke is shortened by untightening the lock nut (19) and clockwise rotation of the adjustment spindle (20). For this, the control chamber has to be depressurized.
