Maximum actuating force and safety for tunnel smoke extraction
Electric actuators
of the QT-XL series
The new performance class from pi safety
With the actuators of the QT-XL series, we are setting new standards for the automation of large damper and valve drives. This newly developed generation of electric actuators combines enormous power with a compact design that is unique in its class.
Whether for demanding tunnel smoke extraction or complex industrial processes: the actuators of the QT-XL series impress with a torque of up to 300 Nm and ensure maximum safety in critical situations thanks to the mechanical spring return (150 Nm). Despite this performance, the devices weigh less than 25 kg and can be easily installed and maintained thanks to our proven design.
