Block valves and adapters for plate mounting
Hydraulic circuit diagram
- number of ways: 4 (number of hose assemblies connected to ports in neutral position)
- number of positions: 2 or 3 (number of squares adjacent to each other)
- 0 (neutral position)
- a, b (actuated position)
- P (pressure/supply passage)
- T (tank/return passage)
- A, B (working passage)

Selecting a directional valve for plate mounting
During selection consider the following criteria:
- size of directional valve (NG6, NG10, …)
- number of positions (2 or 3)
- type of spool (E, G, H, J, HA, D, other)
- control voltage (24V DC, 220V AC, other)
- working pressure
- flow rate
- additional requirements (e.g. hand lever operated)
Types of directional control valves
| Types of directional control valve | Nominal flow rate | Max. working pressure (passage A, B, P) | Max. return pressure (passage T) |
| NG6 | 60 [l/min] | 315 [bar] | 160 [bar] |
| NG10 | 120 [l/min] | 315 [bar] | 160 [bar] |
