Festo
7843
Stem actuated micro valve S-3-PK-3-B
The Festo 7843 is a directly controlled 3/2-way closed monostable industrial component featuring a poppet valve structural design with a mechanical spring reset method. Built with a polymer and brass housing, this valve operates within a pressure range of -0.95 bar to 8 bar and achieves a normal nominal flow rate of 60 l/min through PK-3 pneumatic working ports. It incorporates a soft sealing principle, requires a 6 N actuating force, weighs 7 g, and supports any mounting position via through-holes.

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.
