Festo
8035221
Pneumatic valve VUWS-LT25-M52-M-N14
The Festo 8035221 is a 5/2-way monostable industrial component featuring a 26.5 mm valve size and a plate seat structural design with a soft sealing principle. This directly controlled pneumatic valve delivers a normal nominal flow rate of 1000 l/min through 1/4 NPT working ports across an operating pressure range of 2.5 bar to 10 bar (0.25 MPa to 1 MPa). Equipped with internal pilot air supply, an adjustable exhaust air function, and a mechanical spring reset, the unit 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.
