The PSF-Q-EX / PSF-Q-M-EX is a multifunctional explosion-proof actuator for industrial valves in various applications with either extending or retracting output stem in case of power failure. It features contactless, non-wearing travel detection with Hall sensor for exact positioning.

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

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