The Bosch Rexroth Z1S10P05-1-4X/F (R901274759) is a high-performance industrial hydraulic valve designed for reliable blocking of oil flow at selected ports. This seat valve is direct actuated with a spool symbol P P and a cracking pressure of . bar. It boasts a maximum pressure capacity and features an electrical connection that adheres to product group specifications. With its mechanical actuation type, this valve has a size rating and supports a max flow rate. The Z1S10P05-1-4X/F offers various types of connections, including interim assembly, with connection diagrams that comply with NFPA T.. R D SizeCETOP D and ISO standards. This model is equipped with FKM seals and is compatible with a wide range of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. It features multiple ports for versatile applications and can be used in different switching positions. The weight of the valve ensures stability in operation. As a sandwich plate valve suitable for vertical stackings, the Z1S10P05-1-4X/F offers porting patterns according to ISO standards. Its design includes one-and two-channel blocking functions for optimal efficiency. The poppet made from high-performance plastic guarantees perfect leaktightness even at low pressures. This corrosion-protected design allows for easy adjustments to special hydraulic fluids by exchanging external seal rings. Furthermore, the Z1S10P05-1-4X/F valve facilitates cost-effective maintenance through individually available check valve installation sets. Optional features include measuring ports and throttle check valves if required by specific applications. With its robust construction and flexible capabilities, this Bosch Rexroth hydraulic valve stands out as an essential component in industrial fluid control systems.
Size 10, P2 → P1, mechanically actuated
Industrial hydraulic valve in a high performance range. Reliable blocking of the oil flow at selected ports.
Unpacked Weight: 2.240 kg
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.

Important information on hydraulic fluids: For more information and data on the use of other hydraulicfluids, please refer to the data sheets above or contact us. There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature. Flame-resistant - containing water: Maximum pressure differential per control edge 50 bar Pressure pre-loading at the tank port > 20 % of the pressure differential, otherwise increased cavitation Life cycle as compared to operation with mineral oil HL, HLP 50 … 100%. Bio-degradable and flame-resistant – containing water: If this hydraulic fluid is used, small amounts of dissolved zinc may get into the hydraulic system. |

Notice:
Length and tightening torque of the valve mounting screws must be calculated according to the components mounted under and over the sandwich plate valve.
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. |
|
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". |
