Festo
577493
Air solenoid valve VUVS-LT20-M32U-MZD-G18-F7
The Festo 577493 is an electrical 3/2-way monostable open industrial component featuring a 21 mm valve size, a 5.2 mm nominal width, and a plate seat structural design with a soft sealing principle. This piloted valve utilizes an external pilot air supply port with a pilot pressure of 2.5 bar to 10 bar, an operating pressure ranging from -0.9 bar to 10 bar, and delivers a normal nominal flow rate of 600 l/min through a G1/8 pneumatic working port. Equipped with an adjustable exhaust air function, a mechanical spring reset method, detenting or non-detenting manual override, and c UL us recognition, it operates with negative overlap and non-reversible flow direction in any mounting position.

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.
