Festo
The Festo 8191831 is a 2-way pneumatic ball valve featuring a quarter-turn actuator, weld-on ends on both sides, and an in-line installation design with an F0710 flange hole pattern that permits mounting in any position. Built for a nominal width DN of 65 and a nominal pressure PN of 63, this component operates within a pressure range of 0.55 MPa to 0.8 MPa and handles media temperatures from -10 °C to 200 °C with a Kv flow rate of 507 m³/h. It supports compressed air, inert gas, water, and neutral liquids, requiring oil lubrication for the operating medium while utilizing a soft sealing principle and a reversible flow direction based on DIN 3202-S13 and ISO 5211 norms.
