Festo
557297
Pressure build-up valve VABF-S6-1-P5A4
The Festo 557297 is an electrically actuated industrial component featuring a piston slide design structure based on the ISO 5599-2 standard with internal pilot air supply, soft sealing principle, and mechanical spring reset. It provides a working pressure of 2 to 12 bar, a switchover pressure presetting of 4 bar, and standard nominal flow rates of 3,000 l/min for ventilation and 3,300 l/min for venting using compressed air in accordance with ISO 8573-1:2010 [7:4:4]. This pressure build-up function valve operates with a permissible voltage fluctuation of +/- 10 percent, requires a minimum switching frequency of once per month for forced dynamisation, and includes a manual override that is detenting or self-resetting via an electrical control signal.
