The Bosch Rexroth Z1S6F30-4X/V (R901086039) is a highly versatile and efficient direct operated check valve designed for sandwich plate mounting. This valve facilitates the leak-free blocking of flow in one direction while allowing free flow in the opposite direction, making it an ideal component for various hydraulic applications where unidirectional flow is required.
Engineered with precision, the Z1S6F30-4X/V features a stroke-limited poppet by a plastic socket, ensuring reliable operation. The installed spring aids in the closing movement of the poppet and maintains it in a closed position when the valve is inactive, thus preventing fluid leakage. The design includes an angle valve section that can connect or close off up to three internal channels, with stop and sealing functions provided by a plug screw.
The Z1S6F30-4X/V is notable for its adaptability, capable of functioning both as an angle valve and as a straight-through valve. It conforms to ISO porting patterns and offers various one- and two-channel blocking functions. For guaranteed leaktightness, the poppet is crafted from high-performance plastic.
This model also boasts corrosion protection and can be easily adjusted to special hydraulic fluids by exchanging external seal rings. Optional measuring ports are available for enhanced functionality, and upon request, this valve can also be configured as a throttle check valve.
In terms of technical specifications, this Bosch Rexroth check valve has a size component series X with a maximum operating pressure of bar and can accommodate maximum flow rates of l/min. It's important to note that when installing in positions where the blue plastic socket faces the plate side, no additional seal ring should be used at that position; however, at the component side, the usual seal ring provides necessary sealing for downstream assembly components.
The included plastic socket serves both as a fitting aid and possesses sealing capabilities; therefore, it must not be removed or damaged during installation or operation to maintain system 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.
