11 Removing the Valve from the System
Danger of injury if valve disassembled under pressure or voltage!
Uncontrolled movement of the system components!
O Make sure that the system is not under pressure or voltage when you
disassemble the valve, coil, electrical connector, or the M8x1 socket.
Contamination during disassembly!
During disassembly, greases or lubricant may escape from the valve.
O Make sure that the environment is not contaminated with greases or lubricant
during disassembly.
1. Stop system operation and protect it against being switched on.
2. Ensure that the useful load has reached a stable position.
3. Make sure that the relevant section of the system is not under pressure and
protect it against being switched on.
4. Remove the electrical connector from the coil.
5. Remove the sensor plug from the controller.
6. Loosen the four mounting screws on the valve and remove the valve from the
base plate.
This concludes the disassembly.
12 Exchanging the Coil
To operate the valve with a different voltage, for example, you can exchange the coil.
1. Proceed as described in steps 1.–4. of chapter "11 Removing the Valve from the
System".
2. Proceed as described in section "Assembling the coil" in chapter 7.
