The Bosch Rexroth Z1S6P05-4X/VSO68 (R901086600) is a high-quality sandwich plate check valve designed for efficient hydraulic flow control. This direct operated check valve facilitates leakage-free blocking in one direction while permitting free flow in the opposite, making it an ideal solution for systems requiring unidirectional flow. The valve's poppet stroke is precisely limited by a durable plastic socket, which, along with an installed spring, ensures the poppet remains closed when the valve is inactive. The spring aids in the closing movement of the poppet to maintain system integrity.
This model offers versatility through its straight-through and angle valve sections. The straight-through section allows for simple linking of channels, while the angle valve section can connect or isolate up to three internal channels with ease. The plug screw plays a crucial role in stopping and sealing functions within the system.
The Z1S6P05-4X/VSO68 is designed with careful attention to installation requirements; it specifies that no additional seal ring should be used when the blue plastic socket is mounted on the plate side to prevent any compromise to its sealing function. However, on the component side, a seal ring ensures a secure seal for downstream assembly components.
This Bosch Rexroth check valve stands out with its corrosion-protected design and compatibility with various hydraulic fluids by simply exchanging external seal rings. Additional features include optional measuring ports and availability as a throttle check valve upon request. It supports maximum operating pressures up to bar and can accommodate maximum flow rates of l/min, making it suitable for diverse hydraulic applications where precise fluid control is essential.

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.
