Festo
540815
Air solenoid valve MDH-5/3G-D-2-M12D-C
The Festo 540815 is an electrically actuated 5/3-way closed piston gate valve featuring a soft sealing principle and a nominal width of 11.5 mm. Operating on 24V DC within a pressure range of 3 bar to 10 bar, this piloted component delivers a normal nominal flow rate of 2300 l/min through ISO 5599-1 size 2 sub-base or G3/8 pneumatic working ports. It incorporates internal pilot air supply, adjustable exhaust air function, non-detenting manual override, mechanical spring reset, and IP65 protection in a 54 mm wide structural design conforming to ISO 5599-1 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.
