Festo
578197
Air solenoid valve VUVS-L25-M52-AZD-N14-F8
The Festo 578197 is a 5/2-way monostable industrial component featuring a 26.5 mm valve size, a 6.9 mm nominal width, and a piston gate valve structural design with a soft sealing principle. This piloted, electrically actuated component delivers a normal nominal flow rate of 1300 l/min through 1/4 NPT pneumatic working ports and operates within a pressure range of -0.09 MPa to 1 MPa. It incorporates an external pilot air supply port, adjustable exhaust air function, pneumatic spring reset, reversible flow direction, and both detenting and non-detenting manual override options. Certified by c UL us (OL) with maritime classification issued by DNVGL-TAA000011J, it supports any mounting position and requires a solenoid coil ordered separately.

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.
