Festo
The Festo 4451868 is a mechanical 3-way ball valve featuring an L bore, a 3/2 valve function, and an Rp3/8 fitting connection with a nominal width DN of 10 and a 10 mm inside diameter. Designed with a soft sealing principle, reversible flow direction, and an F03 flange hole pattern for in-line installation in any mounting position, it handles compressed air, inert gas, water, and neutral liquids across a medium temperature range of -20 °C to 130 °C at a nominal pressure PN of 40. This RoHS-compliant and VDMA24364 Zone III LABS conforming component provides a Kv type L flow rate of 9.4 m³/h, a breakaway torque of 6 Nm at nominal pressure PN, and a slot direction switching position indication aligned with the flow direction based on EN 10226-1 and ISO 5211 norms.
