Fully internal pilot oil routing combined with a current command keeps both the pipework and the signal path quiet. This size 32 valve with spool symbol E1 controls 520 l/min nominal flow at 350 bar and accepts 4 to 20 mA at its on-board electronics.

Two sources of trouble disappear in this build: the external pilot lines and the sensitivity of a voltage command. The size 32 valve is fed and drained internally and runs on 4 to 20 mA, at 520 l/min nominal flow and up to 350 bar.
Key benefits
- Internal pilot oil supply and internal return, only the 4 main ports need piping
- Current command value 4 to 20 mA, immune to voltage drop over long runs
- 520 l/min nominal flow, with flow up to 1600 l/min in size 32
- 350 bar operating pressure, spool symbol E1, 3 switching positions, mounting pattern ISO 4401-10-09-0-05
- NBR seals rated to hydraulic fluid HL, weight 43.24 kg, UKCA to SI2016/1091

Applications
Suited to plants where the valve block and the control cabinet are far apart yet little pipework is wanted. Large plastics machines and test rigs with distributed valve islands are typical. System pressure must reliably cover the minimum pilot pressure.
