Festo
555629
Stem actuated valve VMEM-SCZ-M52-M-G18
The Festo 555629 is a 20 mm wide mechanical industrial component featuring a 5/2 monostable valve function with piston slide design structure and a 4 mm nominal size. It operates with compressed air according to ISO 8573-1:2010 [7:-:-] at a working pressure of -0.95 to 10 bar, a standard nominal flow rate of 500 l/min, and medium and ambient temperatures ranging from -10 to 60 °C. The unit utilizes external piloted air supply with a pilot pressure of 2.5 to 10 bar, a mechanical spring reset, an actuating force of 15.5 N, a maximum force on actuator of 80 N, and a maximum switching frequency of 3 Hz under moderate corrosion stress (CRC 2).
