Festo
577514
Air solenoid valve VUVS-LT20-M32U-MZD-G18-F7-1C1
The Festo 577514 is an electrical 3/2-way monostable open industrial component utilizing a piloted plate seat structural design with a soft sealing principle and negative overlap. This device features a 21 mm valve size, a 5.2 mm nominal width, G1/8 pneumatic working ports, an external pilot air supply port, and a normal nominal flow rate of 600 l/min normalized to DIN 1343. Operating on 24V DC across a pressure range of -0.09 MPa to 1 MPa (-0.9 bar to 10 bar), the unit incorporates a mechanical spring reset, adjustable exhaust air function, non-reversible flow direction, detenting and non-detenting manual override, and IP65 degree of protection with a plug socket as per IEC 60529 in any mounting position, backed by c UL us recognition (OL).

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.
