INTELLIGENT QUARTER-TURN ACTUATORS WITH MECHANICAL FAILSAFE FUNCTION OR MANUAL OVERRIDE
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.
