***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 Z4WEH10E68-4X/6EG24N9TK4 (R900977291) is a state-of-the-art directional spool valve designed for electrohydraulic actuation. This valve is capable of functioning as a shutoff through the valve or as a shutoff short-circuit through the valve, ensuring versatility in its application. With P and T ports allowing free flow in every spool position, it offers consistent and reliable performance. This model features wet-pin DC or AC solenoids, which can be optionally chosen based on the specific requirements of the application. It also allows for an optional auxiliary operating device, enhancing its adaptability to various operational scenarios. The electrical connection is designed for either individual or central connection, providing flexibility in system integration. The Z4WEH10E68-4X/6EG24N9TK4 comes with additional options such as switching time adjustment and stroke setting at the main spool, allowing for precise control over the valve's operation. Moreover, it includes provisions for inductive position switches and proximity sensors that operate without contact, offering enhanced safety and maintenance benefits. With a porting pattern according to ISO standards, this directional spool valve ensures compatibility with a wide range of hydraulic systems. The component series X indicates its robust design capable of withstanding maximum operating pressures up to bar units and handling maximum flow rates expressed in liters per minute. This Bosch Rexroth valve is well-suited for advanced hydraulic applications requiring precise control and reliability. Its comprehensive features make it an ideal choice for those seeking high-quality components in their fluid power systems.

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!

Stroke setting, mounting options

The stroke of the main spool is limited by the stroke setting.

The piston stroke is shortened by untightening the lock nut (17) and clockwise rotation of the adjustment spindle (18). For this, the control chamber has to be depressurized.

Stroke 6 mm (1 rotation = 1 mm stroke)
