Festo
8040573
Air solenoid valve VSCS-B-M32-MD-WA-2AC1-8
The Festo 8040573 is an electrical 3/2-way closed, monostable industrial component featuring a 15 mm width, a normal nominal flow rate of 13.5 l/min, and a 110V AC operating voltage. This directly controlled valve incorporates a soft sealing principle, negative overlap lap, non-reversible flow direction, and a mechanical spring reset method supporting both detenting and non-detenting manual override. Rated to IP65 protection and compliant with ISO 15218 standards, the unit operates within a pressure range of 0.15 MPa to 0.8 MPa (1.5 bar to 8 bar / 21.75 psi to 116 psi) with an off switching time of 20 ms.

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.
