540818
Air solenoid valve JMDH-5/2-D-2-M12D-C
The Festo 540818 is a 5/2-way bistable industrial component featuring a piloted piston gate valve with soft sealing and internal pilot air supply. Built to ISO 5599-1 standards with a 54 mm width, a nominal width of 11.5 mm, and a normal nominal flow rate of 2300 l/min, this electrical actuation valve operates at 24V DC across an operating pressure range of 2 bar to 10 bar. It includes an adjustable exhaust air function, non-detenting manual override, IP65 degree of protection, and ISO code 255 for sub-base size 2 or G3/8 pneumatic working ports with any mounting position and non-reversible flow direction.

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.
