Festo
31002
Air solenoid valve MFH-5/3E-1/4-S-B
The Festo 31002 is an electrically actuated 5/3 exhausted industrial component utilizing a piston gate valve structural design with a soft sealing principle and positive overlap lap. Featuring a 32 mm width, a 10 mm nominal width, G1/4 pneumatic working ports, and an operating pressure range of -0.9 bar to 10 bar, this piloted unit delivers a normal nominal flow rate of 1600 l/min with an adjustable exhaust air function and external pilot air supply port. It includes a mechanical spring reset method, non-detenting manual override, reversible flow direction, 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.
