Festo
The Festo 537554 is an electrical industrial component featuring a 3/2 closed, monostable valve function with a 20 mm valve size and a piston slide design structure. This piloted unit operates with an external pilot air supply at a working pressure of -0.9 to 8 bar, a pilot pressure of 2 to 8 bar, and delivers a standard nominal flow rate of 500 l/min using a soft sealing principle and air spring reset. Electrical actuation is driven by a 110 V AC (50/60 Hz) coil requiring 3.1 VA pick-up power and 2.2 VA holding power, achieving 20 ms switching times for both on and off states alongside IP65 protection and detenting or pushing manual override.
