S series 90°
The S series actuators, motors are equipped with a spring return or fail-safe mode. This allows the motor to open or close a valve without mains voltage and battery.
The S actuator has a spring package which immediately closes or opens the valve in case of loss of mains voltage or incoming alarm. This spring package is made of high-quality spring steel, which means that the springs stay at the correct tension for many years and thus deliver the right power over a long period of time.
The S-series actuator is available in 500Nm, 1300Nm, 2000Nm and 2600Nm. The voltages are available in 24V DC/AC, 120V, 220V, 380V and 440V.
The possible extensions for the S-series consist of a clutch-free manual control, ATEX version, anti-fog heater, extra limit switches, modulating function, potentiometer, floating function and choice of rotation directions.
