SUMMARY:  Check valves: Z1S 6.-4x/

Add to Cart

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

technical illustration-Z1S6E05-4X/V-Check valves: Z1S  6.-4x/

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".
