Festo
8031309
Stem actuated valve VMEF-S-M52-E-N18
The Festo 8031309 is a 20 mm wide mechanical 5/2-way monostable piston gate valve featuring a normal nominal flow rate of 750 l/min and a 1/8 NPT pneumatic working port. Built with a soft sealing principle and positive overlap, this directly controlled valve operates within a pressure range of -0.95 bar to 10 bar and utilizes a pneumatic spring reset method. It holds ATEX certification for zones 1, 2, 21, and 22, supports reversible flow direction, and achieves a maximum switching frequency of 3 Hz under moderate corrosion stress.

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.
