The Bosch Rexroth Z1S10TA50-2TB9-4X/F (R901274728) is a high-performance check valve designed for hydraulic applications requiring leak-free blocking in one direction and free flow in the opposite. This direct-operated check valve is constructed for sandwich plate design, making it suitable for vertical stacking and ensuring compatibility with ISO porting patterns. The Z1S10TA50-2TB9-4X/F features a plastic poppet with a stroke limited by a plastic socket, which also serves as a seal when mounted at the plate side, ensuring no additional seal ring is required at this location.
The installed spring aids in the poppet's closing movement and maintains the valve in a closed position when idle, achieving optimal leak tightness even at low pressures. The design of the plastic socket is crucial as it provides preload due to its protrusion and must not be removed or damaged. Despite potential static pressure changes resulting from hydraulic fluid volume and temperature variations, this valve maintains its integrity without leakage at the seat face.
The Bosch Rexroth Z1S10TA50-2TB9-4X/F offers various one and two-channel blocking functions and includes features such as corrosion protection, easy adjustability for special hydraulic fluids by exchanging external seal rings, and cost-effective maintenance through individually available check valve installation sets. Additionally, it provides options for measuring ports and throttle check valves. With its maximum operating pressure of 350 bar and maximum flow of 50 l/min, this valve ensures reliable performance in demanding hydraulic systems.

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.
