Product description
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.

Mounting
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.
Information
- 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". |
