Festo
555622
Stem actuated valve VMEM-STCZ-M32C-M-G18
The Festo 555622 is a 20 mm wide mechanical industrial component featuring a 3/2 closed, monostable valve function with a poppet seat design structure and a 4 mm nominal size. It delivers a standard nominal flow rate of 500 l/min across an operating pressure range of -0.95 to 8 bar, utilizing an external pilot air supply with a pilot pressure of 3.5 to 8 bar, a mechanical spring reset, and an actuating force of 15.5 N with a maximum actuator force of 80 N. Operating within a medium and ambient temperature range of -10 to 60 °C, the unit requires compressed air in accordance with ISO8573-1:2010 [7:-:-] where lubricated operation is possible, exhibits a CRC 2 moderate corrosion stress classification, and has a maximum switching frequency of 3 Hz while strictly prohibiting use as a mechanical stop.
