Festo
8191834
Ball valve unit VZBA-A-1/4-WW-63-T-22-F0304-V4V4T-PB20
This Festo 8191834 industrial component is a 2-way pneumatic ball valve featuring a quarter-turn actuator, soft sealing principle, and weld-on ends for in-line installation in any mounting position. Built with an F0304 flange hole pattern, a nominal width DN of 8, and a nominal pressure PN of 63, it operates at pressures from 0.55 MPa to 0.8 MPa with a breakaway torque of 6 Nm and a flow rate Kv of 7 m³/h based on DIN 3202-S13 and ISO 5211 norms. The reversible 2/2 valve handles a medium temperature range of -10 °C to 200 °C, utilizing compressed air, inert gas, water, or neutral liquids with slot direction matching the flow direction for switching position indication.

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.
