Festo
534303
Ball valve VAPB-3/8-F-40-F03
The Festo 534303 is a mechanical 2-way soft-sealing ball valve featuring a 2/2 valve function, a 10 mm inside diameter, and a DN 10 nominal width with Rp3/8 fitting connections. Designed for in-line installation in any mounting position based on the ISO 5211 norm with an F03 flange hole pattern, it accommodates compressed air as per ISO 8573-1:2010 [-:-:-], inert gas, water, and neutral liquids at medium temperatures ranging from -20 °C to 150 °C. This RoHS compliant component handles a nominal pressure PN of 40 and a reversible flow rate Kv of 9.4 m³/h, requiring a breakaway torque of 3.5 Nm at 10 bar differential pressure and 5 Nm at nominal pressure PN, with switching position indication indicated by slot direction matching flow direction.

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.
