Festo
31003
Air solenoid valve MFH-5/3B-1/4-S-B
The Festo 31003 is a 32 mm wide electrical 5/3-way pressurized industrial component featuring a piston gate valve structural design with a soft sealing principle and positive overlap lap. This piloted unit achieves a normal nominal flow rate of 1600 l/min through G1/4 pneumatic working ports, operating across a pressure range of -0.9 bar to 10 bar with external pilot air supply. It incorporates a mechanical spring reset method, adjustable exhaust air function, non-detenting manual override, and supports any mounting position with a pilot pressure of 3 bar to 10 bar.

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.
