***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth Z1S10TA05-2TB9-4X/F (R901274760) is a mechanically actuated industrial hydraulic valve designed for reliable blocking of oil flow at selected ports. This seat valve is directly actuated, with a cracking pressure specified by the manufacturer, and features the spool symbol TA TA. It can withstand a maximum pressure as indicated in its specifications and has an electrical connection described in its product details. The model Z1S10TA05-2TB9-4X/F is notable for its size and TA TA configuration, accommodating a maximum flow rate as per its design. The type of actuation is mechanical, and it offers an interim assembly connection. The connection diagrams adhere to NFPA T.. R D SizeCETOP D and ISO standards, ensuring compatibility with various systems. This valve has a specific number of switching positions and weighs a certain amount with FKM seals. Designed to work with a range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR, this Bosch Rexroth valve ensures versatility across different applications. It guarantees perfect leak-tightness due to the high-performance plastic used for the poppet construction. The corrosion-protected design enhances durability while allowing easy adjustment to special hydraulic fluids by exchanging external seal rings. This model also offers cost-effective maintenance options through individually available check valve installation sets. Optional features include measuring ports and throttle check valves which can be added according to user requirements. Its sandwich plate design makes it suitable for use in vertical stackings with porting patterns conforming to international standards ISO 4401-03-02-0-05 and ISO 6263-03-02-0-05. The maximum operating pressure and flow rate are defined by the component series X parameters provided by Bosch Rexroth for this specific model code Z1S10TA05-2TB9-4X/F (R901274760).

Unpacked Weight: 2.260 kg

Sandwich plate valve for use in vertical stackings Porting pattern according to ISO 4401-05-04-0-05 and ISO 4401-05-05-0-05 Various one and two-channel blocking functions Perfect leak-tightness due to poppet made of high-performance plastic Corrosion-protected design Easily adjustable to special hydraulic fluids by exchanging the external seal rings Cost-effective replacement of wear parts thanks to individually available check valve installation sets With measuring ports, optional Throttle check valve, optional

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.

Valve housing (steel) and plastic spool with plastic socket can be disassembled into individual components for proper disposal. Deviating from ISO 4401, port T is referred to with TA and port T1 is referred to with TB in this data sheet. The check valve installation set is available separately (plastic socket, plastic spool, spring): E-Mail: spare.parts@boschrexroth.de The plastic socket has a sealing function and may therefore not be damaged. For assembly and disassembly of the check valve installation set, a special multi-purpose tool is required, see "Assembly".

Troubleshooting

External leakage at the flow passages	Seal ring faulty.	Replace seal rings (seal kit).
	Lip of the plastic socket is damaged.	Replace check valve installation set. 1)
	Mounting screws tightened unevenly.	Loosen screws and tighten them again crosswise using the recommended tightening torque.
Internal leakage at the check valve installation set	Foreign particle on poppet surface.	Check poppet surface from the outside for foreign particles and remove them.
	Poppet does not move freely.	Check free movement of the poppet from the outside using an appropriate mandrel. Do not push the plastic socket out of the housing!
	Leakage caused by downstream assembly.	Check if the check valve installation set is the reason for the leakage.
	Hydraulic fluid quality does not correspond to the specification.	Check hydraulic fluid quality and adjust it to the specifications, if required.
	Dependent on the included hydraulic fluid volume and its temperature variations, there may be pressure changes which are not due to leakage.
	If the measures described above are not successful.	Completely replace the check valve installation set. 1)
External leakage at measuring points	Seal faulty.	Replace profile seal.
External leakage at measuring points	Plug screw or fitting not tightened correctly.	Tighten plug screw or fitting using the specified tightening torque.

1)	Use the special multi-purpose tool to avoid damaging the plastic socket, see "Mounting".
