Festo
8191821
Ball valve unit VZBA-A-3-GG-63-T-22-F0710-V4V4T-PB300
The Festo part number 8191821 is a pneumatic 2-way ball valve featuring a quarter turn actuator and a soft sealing principle for in-line installation in any mounting position with an Rp3 fitting connection. Operating at a pressure range of 0.55 MPa to 0.8 MPa (5.5 bar to 8 bar) with a nominal pressure PN of 63, this DN 80 component delivers a Kv flow rate of 905 m³/h and a breakaway torque of 112 Nm at nominal differential pressure based on DIN 3202-M3, EN 10226-1, and ISO 5211 norms. It accommodates a medium temperature range of -10 °C to 200 °C for compressed air, inert gas, water without water vapor, and neutral liquids, utilizing an F0710 flange hole pattern and visual switching position indication via slot direction.
