Festo
8191839
Ball valve unit VZBA-A-11/4-WW-63-T-22-F0405-V4V4T-PB60
The Festo 8191839 is a pneumatic 2-way ball valve featuring a quarter turn actuator and soft sealing principle for in-line installation in any mounting position. Designed with weld-on ends and an F0405 flange hole pattern, this DN 32 valve operates at a nominal pressure of PN 63 and supports a flow rate Kv of 105 m³/h with reversible flow direction. It functions across a medium temperature range of -10 °C to 200 °C using compressed air, inert gas, water without water vapor, neutral liquids, or other requested flow media, requiring an operating pressure between 0.55 MPa and 0.8 MPa.

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.
