The most widely used hydraulic valve interface size in industrial manufacturing. We manufacture high-precision NG10 (CETOP 5 / 06-Size) manifold blocks — the universally adopted standard for medium-duty industrial automation up to 120 LPM.
The NG10 and 06-Size designations both refer to the same physical valve interface, governed by ISO 4401 (CETOP 5). The dual naming convention exists because different regions use different terminology:
All three designations are physically identical. A Parker D3W "06-size" directional valve will mount directly onto a Honeywell CETOP 5 (NG10) manifold block — same bolt pattern, same port locations, same O-ring groove sizes.
Understanding the operating limits of the NG10 interface prevents undersizing (which causes dangerous heat generation) or oversizing (which wastes capital). Attempting to run 200 LPM through an NG10 block will create fluid velocity exceeding 6 m/s in the internal galleries, generating severe heat and turbulence that destroys the directional valve internals.
| Parameter | Value |
|---|---|
| ISO Standard | ISO 4401-05-05-0-05 |
| Nominal Flow Capacity | 80 LPM (continuous), 120 LPM (peak) |
| Maximum Working Pressure | 315 Bar (in steel/iron blocks) |
| Mounting Bolt Pattern | 4 × M6 bolts, ISO 4401-05 spacing |
| P Port (Pressure In) | G 1/2" BSPP (or SAE-8) |
| T Port (Tank Return) | G 1/2" BSPP (or SAE-8) |
| A & B Work Ports | G 3/8" BSPP (or SAE-6) |
| Valve Seal Size | D-ring or O-ring to ISO 4401-05 specification |
| Material Options | AL 6061-T6, ST52 Carbon Steel, EN8 Steel |
| Station Configurations | 1, 2, 3, 4, 5, 6, 8 stations |
| Surface Finish | Anodize (AL), Zinc Plate / Black Oxide (Steel) |
| Testing | 100% Hydrostatic at 1.5x WP |
If you are in doubt between NG10 and NG16, calculate your actual circuit flow: Cylinder Bore² × π/4 × Piston Speed = Flow Rate (LPM). Match this to the NG size capacity.
| Design Consideration | NG6 (CETOP 3) | NG10 (CETOP 5) | NG16 (CETOP 7) |
|---|---|---|---|
| Max Flow | 40 LPM | 120 LPM | 250 LPM |
| Typical Cylinder Bore | Up to 63mm | 63mm to 160mm | 100mm to 250mm |
| Block Size (Single Station) | Very compact | Medium (industry standard) | Large |
| Availability | High | Highest (most common) | Medium |
| Port Size | G3/8" | G1/2" | G3/4" |
Standard in-line subplates in Aluminium (≤210 Bar) and ST52 Steel (≤315 Bar). Available with G1/2" BSPP, SAE-8 O-Ring Boss, or SAE Code 61 flange ports in P and T positions.
2-station to 8-station parallel rail manifolds sharing a common P and T gallery. Machined from a single billet of ST52 steel for maximum structural integrity. Available with integrated gauge ports and optional POCV cartridge provisions per station.
Extended subbase bodies designed to stack one or more modular sandwich plates (flow control, pressure reducing, check valve plates) between the subbase and the directional valve, providing circuit modification capability without external pipework.
Purpose-machined NG10-compatible blocks incorporating additional logic cavities for specific circuit functions — such as combined CETOP 5 directional valves plus Sun Hydraulics cartridge-type relief and sequence valves in a single monolithic block.
