Festo
568311
Solenoid valve VUVB-L-B42-ZD-T516-2AC1
The Festo 568311 is a 4/2 bistable industrial component featuring a 20 mm valve size, a piston slide design structure, and an 800 l/min standard nominal flow rate. This electrically actuated, piloted valve operates within a working pressure range of -0.9 to 8 bar, utilizes external pilot air supply with 2 to 8 bar pilot pressure, and incorporates soft sealing with an IP65 protection class. Powered by 110 V AC at 50/60 Hz with a pick-up power of 3.1 VA and holding power of 2.2 VA, the unit delivers a 20 ms switching time reversal and features detenting, pushing manual override alongside a nominal size of 7 mm, 2.5 kV surge strength, and a degree of contamination of 3.
