Festo
The Festo 8191917 industrial component is a 2-way soft-sealing ball valve paired with a pneumatic quarter-turn actuator, featuring an Rp1/4 fitting connection and an F03 flange hole pattern for in-line installation in any mounting position. Designed with a DN 15 nominal width, a PN 40 nominal pressure, a Kv flow rate of 5.9 m³/h, and a 5 Nm breakaway torque at nominal differential pressure, it operates at pressures between 0.55 MPa and 0.8 MPa (5.5 bar to 8 bar) across a medium temperature range of -10 °C to 200 °C. Compatible with compressed air, inert gas, water, and neutral liquids based on EN 10226-1 and ISO 5211 norms, this unit utilizes slot-direction flow indication and allows for reversible flow.
