5. Product modification
An overview of possible valve modifications is described in the ordering code.
The number of spool positions, the spool connection and the type of emergency control and the electrical parameters of the coil cannot be
subsequently changed by the user.In the case of a valve with a 10 W coil, the coil surface temperature and the application for the temperature class
can be affected by adjusting the ambient temperature (see 4.4 Ambient temperature range for each class).
The coils with AC power supply and built-in rectifier are supplied with only the cable attached, with optional lengths of 3 and 8 m as standard.
