NG6 (Cetop 3)
CETOP 3 valves, also called NG6 or D03, mount on a subplate with the standard ISO 4401-03 interface. They are the most widely used subplate valves in small and medium power units, for flows up to about 60 to 80 l/min depending on the model.
Here you will find:
- Duplomatic DS3 directional solenoid valves, with the various spools (for example S2, S3, RK, 23TB) and DC and AC coils;
- NG6 modular (sandwich) valves: relief, flow control, pilot-operated check and pressure-reducing valves, stacked between the subplate and the solenoid valve;
- NG6 proportional valves for pressure and flow.
How to choose: (1) the spool, i.e. what the valve does in each position (see the symbol on the nameplate or product page); (2) the coil voltage and current type; (3) the type of control (with or without manual override). The code on the old valve's nameplate tells you all of this: search for it.
To find the equivalent from another brand, see the page of NG6 valve equivalents. Replacement coils are in Coils and subplates and manifolds in Manifold blocks and subplates.

NG10 (Cetop 5)
CETOP 5 valves, also called NG10 or D05, mount on a subplate with the standard ISO 4401-05 interface. They handle larger flows than CETOP 3 valves, in medium-power units and machines.
Here you will find Duplomatic DS5 directional solenoid valves, with the various spools and DC and AC coils, DSP5 pilot-operated solenoid valves, DSE5 proportional valves and NG10 modular valves.
How to choose:
- the spool: the connection pattern in each position (closed centre, open centre, tandem…), shown on the valve's nameplate;
- the coil: voltage (12 V, 24 V DC, 110 or 230 V AC) and connector type;
- the maximum flow and pressure of the circuit;
- for pilot-operated valves, whether the pilot and the drain are internal or external.
The interface is standard: a CETOP 5 valve from another brand fits the same subplate, but always check the spool. The code on the old valve is the shortest route: search for it in the search box. Replacement coils are in Coils.
