Custom Manifold Blocks Manufacturer
When standard CETOP blocks cannot solve the problem, we design the solution from scratch. We engineer completely bespoke hydraulic logic blocks for Special Purpose Machines, complex OEM automation circuits, and high-performance test rigs.
Consolidate Your Circuit. Eliminate Every Leak.
We take your hydraulic schematic and transform it into a single, precision-machined monolithic block — eliminating every external fitting, every hose, and every potential leak point from your machine's logic centre.
Standard CETOP subplates and multi-station blocks solve the majority of industrial automation challenges. However, for specialized OEMs requiring absolute logic density, highly specific internal cross-porting, or the integration of advanced screw-in cartridge valves, a custom manifold block is the only viable engineering path.
Cartridge Valve Integration
Our primary specialty within custom manifold design is the integration of screw-in cartridge valves. Unlike CETOP valves, cartridges screw directly into a machined cavity within the block body, making them completely internal and invisible from the outside.
We machine cavities to the exact specifications of leading cartridge valve brands:
- Sun Hydraulics / Hydraforce
- Bosch Rexroth (SE, SL, SP series)
- Parker Hannifin logic elements
- Bucher Hydraulics logic cartridges
When Do You Need a Custom Manifold Block?
Space is Critically Constrained
The machine frame cannot accommodate a standard multi-station block layout. A custom block is machined to the exact external dimensions that fit the available space.
Cartridge Valves Are Required
Screw-in cartridge valves provide far superior logic density than CETOP valves. Integrating them requires custom cavities machined to proprietary specifications.
Circuit-Specific Logic
The system requires a unique internal port interconnection—for example, a cylinder that must regenerate its own return oil into the advance port.
Leak Elimination is Paramount
In food processing, clean-room manufacturing, or precision test rigs, even a single external fitting is unacceptable. A monolithic block eliminates all external interconnections.
Thermal Management
We can machine integral cooling galleries inside the block body itself, circulating coolant water through the block to extract heat generated by high-flow proportional valves.

Custom Block vs. Standard Block
Decision Matrix
| Design Factor | Custom Manifold Block | Standard CETOP/Multi-Station Block |
|---|---|---|

The Custom Manifold Design Process
Our Custom Hydraulic System Design division follows a rigorous, stage-gated design process to guarantee first-time success.
Circuit Analysis
We receive your hydraulic schematic (P&ID) and your machine's space constraints. Our engineers analyse every valve, every flow path, and every pressure requirement.
3D Spatial Layout (CAD)
We model the complete manifold block in 3D CAD. We plan every internal gallery, checking for wall thickness compliance, intersection angles, and plug positions. Every gallery bore is sized for velocity below 6 m/s.
Client Review
We provide the complete 3D model and a detailed PDF layout drawing for your review. You verify port positions, mounting orientations, and access for wrench clearance before a single gram of metal is cut.
CNC Machining
Approved designs enter our CNC machining centre. Deep-hole drilling rigs execute the gallery bores. 5-axis machining centres cut the cartridge valve cavities to the valve manufacturer's exact specifications.
Hydrostatic Leak Testing
The completed block is sealed, connected to our test rig, and pressurized to 1.5x maximum working pressure. We verify zero internal cross-port leakage and zero external leakage.
Documentation
You receive a complete technical dossier: the 3D STEP CAD model, PDF manufacturing drawing, internal gallery schematic, bill of materials (valve cavities and plugs), and the hydrostatic test certificate.
