The Bosch Rexroth Z1S6P30-4X/V (R901086052) is a high-performance industrial hydraulic valve that offers reliable blocking of oil flow at selected ports through its direct-actuated seat valve design. It features a mechanically actuated spool with the symbol P P, ensuring efficient function for various hydraulic applications. This model boasts a maximum pressure capacity and includes an electrical connection description that aligns with its robust capabilities. Designed for versatility, the Z1S6P30-4X/V valve can be utilized both as an angle valve and as a straight-through valve, depending on the requirements of the system. It conforms to ISO porting patterns and offers multiple one- and two-channel blocking functions. The construction of this valve ensures perfect leaktightness due to its poppet made from high-performance plastic, while its corrosion-resistant design extends its service life even in demanding environments. The valve is equipped with a number of ports and offers ease of integration into vertical stacking systems. The maximum flow rate it can handle is specified, which allows users to match it precisely to their system's needs. Connection options are broad, including interim assembly connections detailed in corresponding NFPA and CETOP diagrams. For maintenance and customization purposes, the external seal rings can be exchanged to adapt the valve for use with various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. Additionally, optional measuring ports are available for enhanced monitoring capabilities. On special request, this model can also function as a throttle check valve. Lastly, the weight of the Z1S6P30-4X/V along with its size specifications are provided to ensure proper fitment in system layouts. Seals made from FKM guarantee durable performance under various operational conditions.
Size 6, P2 → P1, mechanically actuated
Industrial hydraulic valve in a high performance range. Reliable blocking of the oil flow at selected ports.
Unpacked Weight: 0.78 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 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 poppet (1) in closed position.
In contrast to the straight-through valve (section 1), the angle valve (section 2) links or closes off up to three internal channels. Stop and sealing function are taken over by the plug screw (4).
Notice:
For all installation positions in which the blue 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 (5) (as usual) seals the assembly installed downstream.
The installed plastic socket (2) has a sealing function and may not be removed or damaged.

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. |

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.
Notes
Valve housing (steel) and plastic spool with plastic socket can be disassembled into individual components for proper disposal. 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 installation and disassembly of the check valve installation set, a special multi-purpose tool is required, see "Mounting".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. Caution - 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". |
