Total price
Many installed controllers simply put out the command value as ±10 V. This valve accepts that signal directly, works with spool symbol E, 325 l/min nominal flow and an internally routed pilot circuit.
Benefits
- ±10 V analogue input, directly compatible with common axis controllers and process control systems
- 325 l/min nominal flow, operating pressure up to 350 bar, valve maximum 870 l/min
- Internal pilot circuit, so neither a pilot pump nor additional piping is needed
- Spool symbol E, three switching positions, four ports
- Mass 20.66 kg, FKM seals, HL hydraulic fluid

Application
The valve is used when replacing older proportional valves in existing plant whose control system offers only a voltage output. The internal pilot circuit keeps the conversion work on the manifold small. Spool symbol, nominal flow and the permissible return loading have to be checked.
