Festo
31317
Air solenoid valve MFH-5/3G-3/8-S-B
The Festo 31317 is an electrical 5/3-way closed piston gate valve featuring a nominal width of 12 mm, a 40 mm width, and a normal nominal flow rate of 2200 l/min through G3/8 pneumatic working ports. This piloted component operates within a pressure range of -0.09 MPa to 1 MPa using an external pilot air supply port, a mechanical spring reset method, and a soft sealing principle with adjustable exhaust air function. Additional specifications include non-detenting manual override, reversible flow direction, positive overlap lap, any mounting position, and a pilot pressure of 0.3 MPa to 1 MPa.

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.
