Festo
10403
Stem actuated micro valve SO-3-PK-3-B
The Festo 10403 is a mechanical 3/2-way monostable open industrial component featuring direct control, a nominal width of 1.8 mm, and a normal nominal flow rate of 60 l/min normalized to DIN 1343. Operating between -0.95 bar and 8 bar, this 7 g brass and POM valve requires a 6 N actuating force and utilizes PK-3 pneumatic connections for ports 1 and 2, along with a mechanical spring reset method and through-hole mounting. It conforms to VDMA24364 Zone III LABS standards and functions within an ambient temperature range of -10 °C to 60 °C.

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.
