Festo
571425
Vacuum generator VABF-S4-1-V2B1-C-VH-20
The Festo part number 571425 is a non-modular industrial component featuring a 2 mm Laval nozzle nominal width, an open muffler construction type, and reverse polarity protection across all electrical connections. It operates within a 4 bar to 8 bar operating pressure range at a 6 bar nominal operating pressure and a DC operating voltage range of 21.6 V to 26.4 V, utilizing a piezoresistive measuring principle for relative pressure with a threshold value comparator switching function. Integrated functions include an electric ejector pulse valve, flow control valve, electric on-off valve, electric air-saving function, check valve, open muffler, and vacuum switch alongside a 5/3-way pressurized valve function and N.O. contact switching element function.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
