Festo
8191902
Ball valve unit VZBE-A-2-T-63-T-2-F0507-V15V15-PA60
The Festo 8191902 is a 2-way pneumatic ball valve featuring a quarter-turn actuator, a soft sealing principle, and a nominal width DN of 50 with a 2 NPT fitting connection. This in-line mountable component operates within a pressure range of 0.55 MPa to 0.8 MPa and a medium temperature range of -10 °C to 200 °C, delivering a Kv flow rate of 420 m³/h based on ASME B1.20.1 and ISO 5211 norms. Compatible media include compressed air, inert gas, water without water vapor, and neutral liquids, utilizing an F0507 flange hole pattern and providing a breakaway torque of 44 Nm at nominal fitting PN 63 pressure.

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.
