577509
Air solenoid valve VUVS-LT20-T32U-MD-N18-F7
The Festo 577509 is a 21 mm electrical industrial component featuring a 2x3/2 open monostable valve function, internal pilot air supply port, and a plate seat structural design with soft sealing. It delivers a normal nominal flow rate of 600 l/min through 1/8 NPT pneumatic working ports across an operating pressure range of 0.25 MPa to 1 MPa (2.5 bar to 10 bar). Equipped with a mechanical spring reset method, adjustable exhaust air function, and both detenting and non-detenting manual override, this c UL us-recognized unit operates with a piloted control type 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.
