Festo
556902
Stem actuated valve VMEM-ST-M32U-M-G14
The Festo 556902 is a 25 mm wide mechanical industrial component featuring a 3/2 open, monostable valve function with a direct type of piloting and poppet seat design structure. This unit delivers a standard nominal flow rate of 1,000 l/min across a working pressure range of -0.95 to 8 bar, utilizing a mechanical spring reset and requiring an actuating force of 140 N with a maximum actuator force of 280 N. Weighing 198 g with a 6 mm nominal size and CRC 2 moderate corrosion resistance, it operates with compressed air according to ISO8573-1:2010 [7:-:-] at temperatures between -10 and 60 °C, and must not be used as a mechanical stop.
