PSF Quarter-Turn Actuators

Based on the proven PSF linear actuators we recently developed a new actuator series with mechanical fail safe function or manual override.

The PSF-Q / PSF-Q-M is a multifunctional actuator for industrial valves in various applications with either extending or retracting output stem in case of power failure.

PSF-Q: integrated power spring causes the fail safe in the case of loss of power supply

PSF-Q-M: manual override can be operated by using the hand wheel or the two buttons of the local control.

Due to its robustness and small dimensions the PSF-Q/PSF-Q-M series is an interesting extension of the product range for the industrial as well as the heating, ventilation and air-conditioning sectors.

Robust industrial design with polycarbonate cover, enclosure IP65 (IP67 optional)

Contactless, non-wearing travel detection with Hall sensor for exact positioning

Brushless DC motor (BLDC). Controller with integrated positioner function.
