NOTE
1 )
Pause time with change of rotation 0.4 s.
2 ) Increased wear with continuous operation of the motor.
3 ) limited gas seal
4 )
Impurities (e.g., fluff etc.) should be pre-filtered, otherwise the function of the valve could be impaired.
5 ) At 24 V DC smoothed. Pulsed drive increases the rotation time (see also
6 ) dependent on pressure/load
7 ) Higher currents considerably reduce the service life!
8 ) Higher temperatures limit the max. power loss of the potentiometers.
