The Bosch Rexroth Z4WH22E63-5X/ (R900501680) is a high-performance directional spool valve designed for hydraulic operations. This pilot-operated valve offers versatility in its functioning, allowing for shutoff through the valve or short-circuit through the valve while maintaining free flow in P and T in every spool position. The porting pattern of this model adheres to ISO standards, ensuring compatibility and ease of integration into various hydraulic systems. Equipped with wet-pin DC or AC solenoids that can be optionally chosen, the Z4WH22E63-5X/ provides flexibility for different electrical system requirements. For further customization, there's an optional auxiliary operating device with an electrical connection available as an individual connection, with a central connection provided upon request. Additionally, this model can be tailored to specific application needs through optional features such as switching time adjustment and stroke setting at the main spool. The Z4WH22E63-5X/ is engineered to withstand maximum operating pressures (bar) and accommodate maximum flow rates (l/min), ensuring reliable performance even under demanding conditions. Furthermore, for enhanced operational accuracy and safety, the valve can be equipped with inductive position switches and proximity sensors that offer contactless detection features. These advanced components contribute to precise control and extended service life of the valve. Designed by Bosch Rexroth, a leader in drive and control technologies, this directional spool valve is a testament to their commitment to innovation and quality engineering. The Z4WH22E63-5X/ (R900501680) stands out as a robust solution for efficient control within hydraulic systems across various applications.

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.

Notice!
Length and tightening torque of the valve mounting screws must be calculated according to the components mounted.
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 (19) and clockwise rotation of the adjustment spindle (20). For this, the control chamber has to be depressurized.
