The Bosch Rexroth Z4WH 10 E63-4X//V (R900928019) is a high-performance directional spool valve, which is pilot-operated and designed for hydraulic applications. It features the versatility of functioning either as a shutoff valve or for shutoff short-circuit through the valve, with P and T ports allowing free flow in every spool position. This model conforms to the ISO porting pattern standard, ensuring compatibility with various hydraulic systems. Equipped with wet-pin DC or AC solenoids that can be chosen based on system requirements, this directional spool valve offers flexibility for electrical connections, providing options for either individual or central connection setups. For enhanced operational control, it includes optional features such as switching time adjustment and stroke setting at the main spool, which allow for precise manipulation of the valve's performance according to specific application needs. Additionally, this model can be fitted with optional auxiliary operating devices to expand its functionality. The Z4WH 10 E63-4X//V also supports the integration of inductive position switches and contactless proximity sensors that contribute to improved accuracy and reliability in position sensing. This component falls under series X by Bosch Rexroth and is engineered to withstand a maximum operating pressure of up to bar while accommodating a maximum flow rate of l/min. Its robust design ensures reliable operation even under demanding conditions, making it suitable for a wide range of hydraulic applications where precise control of fluid direction is critical.

Notes!
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 actuation, separate order, material no. R900024943). When the manual override is blocked, the operation of the solenoid must be prevented! The simultaneous actuation of the solenoids must be prevented!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.
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.
