***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 Z4WH16E63-5X/ (R900502420) is a state-of-the-art directional spool valve designed for hydraulic operations, featuring pilot operation and the capability to function as a shutoff valve or a shutoff short-circuit through valve. Its design allows for free flow in every spool position, even when P and T ports are involved. The porting pattern of this component is in accordance with ISO standards, ensuring compatibility and ease of integration into various hydraulic systems.
This model is equipped with wet-pin DC or AC solenoids that can be selected based on the specific requirements of the application. Additionally, it offers an optional auxiliary operating device with an electrical connection that can be configured as an individual connection, with a central connection available upon request. For applications requiring precise control, the Z4WH16E63-5X/ includes options for switching time adjustment and stroke setting at the main spool to fine-tune performance.
Furthermore, it supports the use of inductive position switches and proximity sensors that operate without contact for enhanced operational reliability and accuracy. With its robust design, this valve is capable of handling maximum operating pressures up to bar and sustaining maximum flow rates up to l/min. The Z4WH16E63-5X/ represents Bosch Rexroth's commitment to quality and performance in hydraulic system components.

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.
