Subplates
Accessories for valves
Festo subplates allow standards-compliant mounting of directional control valves on manifold blocks or as individual connections. The 158-article range covers four main groups: single sub-base plates (NAS-1A-ISO to NAS-4A-ISO and VDMA variants), under sub-base plates (NAU-1B to NAU-4B-ISO), chaining plates (NAV-1C to NAV-4C-ISO and angle chaining plates NAVW), and angle sub-base plates (NAW). Pressure-regulating intermediate plates (LR-ZP-A/B/P-D-3) complement the programme.
Port sizes follow the ISO 5599-1 scale: size 1 (1/8 inch), 2 (3/8 inch), 3 (1/2 inch) and 4 (3/4 inch). VDMA variants conform to the older VDMA standard and cover 1/4- and 1/8-inch ports.
| Type | ISO size | Port | Function |
|---|---|---|---|
| NAS-1/8-1A-ISO | 1 | G1/8 | Single sub-base plate |
| NAS-3/8-2A-ISO | 2 | G3/8 | Single sub-base plate |
| NAS-1/2-3A-ISO | 3 | G1/2 | Single sub-base plate |
| NAS-3/4-4A-ISO | 4 | G3/4 | Single sub-base plate |
| NAV-1/4-1C-ISO | 1 | G1/4 | Chaining plate |
| NAVW-1/4-1-ISO | 1 | G1/4 | Angle chaining plate |
| LR-ZP-A-D-3 / -P-D-3 | - | G3/8 | Pressure regulator intermediate plate |
Typical applications: Building standards-compliant valve manifold blocks to ISO 5599-1 for Tiger 2000 and Tiger Classic series, converting from VDMA to ISO valve format with identical pipework, individual pressure zone separation using NAV chaining plates, and pressure reduction at individual valve positions with LR-ZP intermediate plates.
