Festo
3394
Stem actuated valve VS-4-1/8
The Festo part number 3394 is a 4/2-way monostable industrial component featuring a mechanical actuation type, plate seat structural design, and soft sealing principle. This piloted valve operates within a pressure range of 0.35 MPa to 0.8 MPa and delivers a normal nominal flow rate between 140 l/min and 147 l/min through G1/8 pneumatic working ports with an adjustable exhaust air function. Built with internal pilot air supply and mechanical spring reset, the unit achieves a corrosion resistance class of 2 and holds ATEX certification for zones 1, 2, 21, and 22.

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.
