Festo
556901
Stem actuated valve VMEM-ST-M32C-M-G14
The Festo 556901 is a 25 mm wide mechanical industrial component featuring a 3/2 closed, monostable valve function with direct piloting and a poppet seat design. Delivering a standard nominal flow rate of 1,000 l/min across a working pressure range of -0.95 to 8 bar, this 198 g direct-actuated unit utilizes a mechanical spring reset and requires an 80 N actuating force with a 280 N maximum force limit on the actuator. Operating medium is compressed air in accordance with ISO8573-1:2010 [7:-:-] within a temperature range of -10 to 60 °C, supporting lubricated operation and featuring a CRC 2 moderate corrosion resistance classification.
