The Bosch Rexroth Z1S10TA05-2TB9-4X/N (R901274777) is a high-quality direct operated check valve designed for leak-free blocking in one direction while allowing free flow in the opposite. This sandwich plate valve is suitable for vertical stacking applications and adheres to ISO porting patterns, ensuring compatibility with standardized systems. The model features a stroke-limited plastic poppet, which is secured by a plastic socket that also serves as a seal when mounted at the plate side, negating the need for an additional seal ring at this position.
The spring installed within the valve aids in closing movements and maintains the poppet in a closed position when there's no fluid flow, achieving optimal leaktightness even at low pressures. The design of the Z1S10TA05-2TB9-4X/N accounts for static pressure variations due to changes in hydraulic fluid volume and temperature without resulting from seat face leakage.
This Bosch Rexroth check valve showcases a corrosion-protected design and can be easily adjusted for use with special hydraulic fluids by exchanging external seal rings. It offers cost-effective maintenance options through individually available check valve installation sets. Additionally, it comes with optional features such as measuring ports and throttle check valves to enhance functionality.
With its size and component series X, the valve can withstand a maximum operating pressure of up to bar and can handle maximum flow rates of l/min. This makes it an ideal choice for various one-channel and two-channel blocking functions where perfect leaktightness is required, along with high-performance plastic components that ensure durability and reliability in demanding applications.

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.
