Festo
558370
Air solenoid valve VUVB-ST12-B52-ZH-QX-D-1T1
The Festo 558370 is a 24 mm bistable 5/2-way electrical industrial component featuring a poppet valve design with a self-holding function and soft sealing principle. It delivers a normal nominal flow rate between 260 l/min and 450 l/min across an operating pressure range of 2.8 bar to 8 bar, utilizing QS-4 or QS-6 pneumatic working ports and an external pilot air supply. Equipped with an IP65 degree of protection, non-detenting manual override, and a rapid 10 ms changeover time, this piloted unit supports 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.
