Festo
546778
Air solenoid valve VSVA-B-M52-MZH-A2-1R5L
The Festo 546778 is an electrical 5/2-way monostable industrial component featuring a piston gate valve structural design and a nominal width of 5 mm with an 18 mm width. Operating on 24V DC within a pressure range of -0.09 MPa to 1 MPa (-0.9 bar to 10 bar), this piloted unit achieves a normal nominal flow rate of 550 l/min and incorporates an adjustable exhaust air function, a soft sealing principle, and a non-detenting manual override with mechanical spring reset. It complies with ISO 15407-1 and VDMA 24563 standards for sub-base size 18 mm and connecting plate size 02 ports, carries IP65 protection, and holds C-Tick, c UL us, CE, and UKCA certifications.

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.
