Festo
574271
Pneumatic valve VUWG-L18-B52-G14
The Festo 574271 is a 5/2-way bistable industrial component featuring a 18 mm valve size, a piston gate valve structural design, and a 19 mm width dimension. This pneumatically actuated, directly controlled valve operates within a pressure range of -0.9 bar to 10 bar, delivers a normal nominal flow rate of 1380 l/min, and includes adjustable exhaust air function alongside a soft sealing principle. Operating on compressed air per ISO 8573-1:2010 [7:4:4] with reversible flow direction and positive overlap, the unit supports vacuum applications and permits oil lubrication.

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.
