Festo
568621
Solenoid valve VUVB-S-B42-ZD-T516-1T1L
The Festo 568621 is a 20 mm electrical 4/2 bistable industrial component featuring a piston slide design structure, soft sealing principle, and a nominal size of 7 mm with a standard nominal flow rate of 800 l/min. Operating at a working pressure range of -0.9 to 8 bar and a pilot pressure of 2 to 8 bar with external pilot air supply, this IP65-protected unit includes a pushing manual override, non-reversible flow direction, and a 24 V DC characteristic coil data featuring a 0.1 W low-current phase and a 3.3 W high-current phase. This component achieves a switching time reversal of 25 ms, withstands a surge strength of 0.8 kV under a degree of contamination of 3, and permits assembly in any position with a non-throttleable exhaust-air function.
