Festo
8191827
Ball valve unit VZBA-A-1-WW-63-T-22-F0405-V4V4T-PA20
The Festo 8191827 is a pneumatic industrial component featuring a 2-way ball valve with a quarter-turn actuator and soft sealing principle, engineered for in-line installation with weld-on ends in any mounting position. Complying with DIN 3202-S13 and ISO 5211 standards with an F0405 flange hole pattern, this DN 25 valve operates at pressures from 0.55 MPa to 0.8 MPa and a fitting nominal pressure of PN 63, delivering a Kv flow rate of 71.5 m³/h across a medium temperature range of -10 °C to 200 °C. It supports reversible flow for compressed air, inert gas, water without water vapor, and neutral liquids, exhibiting a breakaway torque of 17 Nm at nominal differential pressure and featuring a slot direction flow position indicator.
