Festo
547174
Air solenoid valve VSVA-B-B52-H-A1-2AC1
The Festo 547174 is a 26 mm, 5/2-way bistable industrial component featuring electrical actuation and a piloted control type with internal pilot air supply. Built with a piston gate valve structural design and soft sealing principle, this unit delivers a normal nominal flow rate of 1100 l/min at an operating pressure ranging from 0.2 MPa to 1 MPa (2 bar to 10 bar). It includes an adjustable exhaust air function, a non-detenting manual override, and a nominal width of 9 mm, while offering IP65 and NEMA 4 protection powered by 110V AC operating voltage. Conforming to ISO 15407-1 and VDMA 24563 standards with sub-base size 26 mm, connecting plate size 01, and G1/4 pneumatic working ports, the hardware carries CE marking per the EU low voltage directive and UKCA marking to UK EMC instructions for 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.
