About hydraulic valves
Cartridge valve Hansa Flex HK CB BY LHN is a flow control element for hydraulic fluid. We supply valves from Danfoss (including former Eaton and Comatrol), Bosch Rexroth, HAWE, HYDAC, Parker and Hansa Flex — genuine parts and quality alternatives.
Classification by function
| Group | What it does | Series |
|---|---|---|
| Check valves | Allow flow in one direction only | CV, PSV, SBV |
| Relief valves | Limit maximum pressure | RV, VMPP, PRV |
| Pressure reducing | Lower pressure in a secondary circuit | PR, MRV |
| Directional (CETOP) | Change flow direction | 4WE6, 4WE10, DKE |
| Proportional | Smoothly regulate flow or pressure | PVG, DHZO |
| Flow control | Stabilise or divide flow | 2FRM, 9RD |
What matters when selecting
- Spool type — 2/2, 3/2, 4/2, 4/3 and centre condition (closed, open, float).
- Pressure — nominal and peak; do not exceed catalogue values.
- Flow — size with 10–20% headroom above working flow.
- Mounting — CETOP (NG6/NG10/NG16/NG25), cartridge, inline or monoblock.
- Actuation — manual, solenoid (12/24 V DC, 110/220 V AC), hydraulic, proportional.
Send us the marking or a photo of the nameplate — we will identify the series, spool type and offer a genuine part or a compatible alternative.
Frequently asked questions
Can a 4WE6 be replaced by a cartridge valve?
Only by reworking the hydraulic circuit and mounting plate. These are different design families — a direct part-for-part swap is not possible.
What if the model is discontinued?
We source a modern equivalent of the same size, or an updated model in the series with recalculated characteristics.
Is a filter needed upstream of the valve?
Yes. Oil contamination is the main cause of spool jamming and loss of tightness. We recommend filtration no coarser than 10 µm for proportional equipment.
