Festo
577533
Pneumatic valve VUWS-LT20-M32U-M-N18
The Festo 577533 is a 5/2-way monostable pneumatic industrial component featuring a 21 mm valve size, a 5.2 mm nominal width, 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, operating within a pressure range of -0.9 bar to 10 bar utilizing a mechanical spring reset and internal pilot air supply. This directly controlled, non-reversible valve includes an adjustable exhaust air function, operates with negative overlap, and carries c UL us recognition without manual override.

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.
