Festo
555627
Stem actuated valve VMEM-SC-M52-M-G18
The Festo 555627 is a 20 mm wide mechanical 5/2 monostable industrial component featuring a piston slide design structure, a nominal size of 4 mm, and a standard nominal flow rate of 500 l/min. Operating with compressed air in accordance with ISO8573-1:2010 [7:-:-] at a working pressure of 2.5 to 10 bar, this piloted valve utilizes internal pilot air supply and a mechanical spring reset with an actuating force of 15.5 N and a maximum force on the actuator of 80 N. The unit weighs 170 g, has a maximum switching frequency of 3 Hz, and functions within medium and ambient temperatures of -10 to 60 °C, featuring a CRC corrosion resistance classification of 2 and allowing for lubricated operation that is subsequently required for further operation while explicitly excluding use as a mechanical stop.
