1 )
increased wear with continuous operation of the motor.
2 )
limited gas seal
3 )
impurities (e.g., fluff etc.) should be pre-filtered, otherwise the function of the valve could be impaired.
4 )
at 24 V dc smoothed. pulsed drive increases the rotation time (see also
5 )
6 ) higher currents considerably reduce the service life!
higher temperatures limit the max. power loss of the potentiometers.
7 )
min. pulse duration (the pulse duration increases for no-load / under load/pressure): approx. 100 ms
