Festo
8191812
Ball valve unit VZBA-A-1/4-GG-63-T-22-F0304-V4V4T-PB20
The Festo 8191812 is a 2-way pneumatic soft-sealed ball valve featuring a quarter-turn actuator designed for in-line installation in any mounting position with an Rp1/4 fitting connection. Built to DIN 3202-M3, EN 10226-1, and ISO 5211 norms, this DN 8 component handles operating pressures from 0.55 MPa to 0.8 MPa and a nominal fitting pressure PN of 63, delivering a Kv flow rate of 7 m³/h across a medium temperature range of -10 °C to 200 °C. It accommodates compressed air, inert gases, water without water vapor, and neutral liquids, requiring oil lubrication for operating media while maintaining a breakaway torque of 6 Nm at nominal pressure.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
