The Bosch Rexroth Z1S6E15-4X/V (R901160944) is a high-quality, direct-operated check valve designed for integration into hydraulic systems. This sandwich plate valve is versatile, offering configurations as both an angle valve and a straight-through valve. It facilitates the leakage-free blocking of flow in one direction while allowing free flow in the opposite direction. The design includes a poppet with a stroke limited by a plastic socket, ensuring reliable operation and perfect leak-tightness. A spring supports the poppet's closing movement and maintains it in a closed position when there is no fluid flow.
This model of the Z1S6E15-4X/V valve boasts several features that enhance its functionality within hydraulic circuits. The angle valve section can link or close off up to three internal channels, while the straight-through section provides traditional check valve operations. The plug screw serves as both a stop and sealing function, ensuring secure operation under various conditions.
The Bosch Rexroth Z1S6E15-4X/V is designed to adhere to ISO porting patterns, allowing for compatibility with standard hydraulic systems. Its maximum operating pressure reaches up to bar, and it can handle maximum flow rates of l/min, making it suitable for a wide range of applications. Additionally, this model offers excellent corrosion protection and can be easily adjusted for use with special hydraulic fluids by exchanging the external seal rings.
Optional features include measuring ports for system monitoring and the capability to function as a throttle check valve upon request. It's important to note that when installing this valve in positions where the blue plastic socket faces the plate side, no additional seal ring should be used at that location; however, at the component side, a seal ring ensures proper sealing of downstream assemblies. The installed plastic socket also serves as a seal and should not be removed or damaged to maintain integrity.

The valve type Z1S is a direct operated check valve in sandwich plate design.
It is used for the leakage-free blocking in one direction and allows for free flow in the opposite direction.
The stroke of the poppet (1) is limited by the plastic socket (2). The installed spring (3) supports the closing movement. When no fluid flows through the valve, the spring (3) keeps the poppet (1) in closed position.
In contrast to the straight-through valve (section 1), the angle valve (section 2) links or closes off up to three internal channels. Stop and sealing function are taken over by the plug screw (4).
Notice:
For all installation positions in which the blue plastic socket (2) is mounted at the plate side ➁, no additional seal ring may be used at this position!
At the component side ➀, the seal ring (5) (as usual) seals the assembly installed downstream.
The installed plastic socket (2) has a sealing function and may not be removed or damaged.
