Festo
8128473
Solenoid valve VSNC-FKA-M52-RD-G18-1C1-S
The Festo 8128473 is a 5/2-way monostable industrial component featuring electrical actuation, a 25.5 mm width, and a normal nominal flow rate of 400 l/min normalized to DIN 1343. Operating on 24V DC within a pressure range of 0.25 MPa to 0.8 MPa (2.5 bar to 8 bar), this piloted piston slide valve incorporates a soft sealing principle, internal pilot air supply, and a NAMUR connection pattern conforming to VDI/VDE 3845 standards. It includes a detenting manual override, mechanical and pneumatic spring reset methods, an adjustable exhaust air function, and an IP65 degree of protection for mounting in any 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.
