Festo
8031299
Stem actuated valve VMEF-S-M52-E-G18
The Festo 8031299 is a 20 mm wide mechanical 5/2-way monostable industrial component utilizing a piston gate valve structural design with a soft sealing principle and positive overlap lap. Featuring a G1/8 pneumatic working port, direct control, and a normal nominal flow rate of 750 l/min, this reversible component operates within a pressure range of -0.95 bar to 10 bar and incorporates a pneumatic spring reset method. Certified for ATEX Zone 1, Zone 2, Zone 21, and Zone 22 explosion prevention and protection, it achieves a corrosion resistance class of 2 and supports compressed air operating media according to ISO 8573-1:2010 [7:-:-] with oil lubrication capability.

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.
