The Bosch Rexroth Z1S10A05-2B05-2-4X/F (R901274767) is a high-performance check valve designed for precise fluid control in hydraulic systems. This direct-operated check valve is crafted to ensure leak-free blocking in one direction while permitting free flow in the opposite, making it ideal for applications requiring unidirectional flow control. Constructed as a sandwich plate design, the Z1S10A05-2B05-2-4X/F valve is compatible with vertical stackings and conforms to ISO porting patterns, ensuring broad compatibility and ease of integration into existing hydraulic circuits.
The valve's functionality is enhanced by the use of a high-performance plastic poppet which is kept in the closed position by a spring when there's no fluid flow, providing optimum leak tightness even at low pressures. The stroke of the poppet is limited by a plastic socket which also has a sealing function and must not be removed or damaged to maintain system integrity. Notably, this model includes features that prevent static pressure changes within the system that are not due to seat face leakage but are instead caused by variations in hydraulic fluid volume and temperature.
The Z1S10A05-2B05-2-4X/F boasts corrosion protection and can be easily adapted to special hydraulic fluids by swapping external seal rings. Additionally, it offers cost-effective maintenance options through individually available check valve installation sets. Optional features for this model include measuring ports and throttle check valves, enhancing its adaptability to various operational requirements. With its size and component series X, it can handle maximum operating pressures of up to bar and maximum flow rates of l/min, making it a robust choice for demanding hydraulic applications where precise fluid control is paramount.

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 plastic 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 plastic poppet (1) in closed position. Optimum leak-tightness is already achieved at low pressures (0.1 x pmax).
Notice:
For all installation positions in which the 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 (as usual) seals the assembly installed downstream.
The installed plastic socket (2) has a sealing function and may not be removed or damaged. Protrusion of the plastic socket (2) is required for design reasons (preload). Dependent on the included hydraulic fluid volume and its temperature variations, static pressure changes, which are not caused by leakage at the seat face, may occur.

Check valve installation set: Disassembly and assembly
Disassembly/assembly without causing damage is achieved by using the special multi-purpose tool (1) (separate order, material no. R901182853).
Disassembly:
Push out the check valve installation set.
Assembly:
Insert the check valve installation set and push in the plastic socket (2).
With correct assembly using the special multi-purpose tool (1), the protrusion of the plastic socket (2) is approx. 0.3 mm.
Notice:
Once removed, plastic sockets may no not be used again.
