Festo
8191811
Ball valve unit VZBA-A-4-GG-63-T-22-F10-V4V4T-PA240
The Festo 8191811 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. It operates within a pressure range of 0.55 MPa to 0.8 MPa (5.5 bar to 8 bar, 79.75 psi to 116 psi) and handles a nominal fitting pressure PN of 63 with a breakaway torque of 140 Nm at nominal differential pressure. Built to DIN 3202-M3, EN 10226-1, and ISO 5211 norms, this DN 100 component with an F10 flange hole pattern provides a reversible flow rate Kv of 1414 m³/h for compressed air, inert gas, water, and neutral liquids across a medium temperature range of -10 °C to 200 °C.

Request a QuoteWhy no listed price?
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.
