Festo
31309
Pneumatic valve VL-5/3E-1/8-B
The Festo 31309 is a pneumatic 5/3 exhausted piston gate valve featuring a width of 26 mm, a nominal width of 8 mm, and a normal nominal flow rate of 1000 l/min normalized to DIN 1343. Designed with a soft sealing principle, a positive overlap, a mechanical spring reset method, and an adjustable exhaust air function, this directly controlled component operates within a pressure range of -0.09 MPa to 1 MPa (-0.9 bar to 10 bar) and requires an external pilot air supply port with a pilot pressure of 0.3 MPa to 1 MPa (3 bar to 10 bar). It includes G1/8 pneumatic working ports, allows for reversible flow direction, and supports any mounting position without a manual override.

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.
