Festo
8191854
Ball valve unit VZBA-A-3/8-GGG-63-32L-F0304-V4V4T-PB40
The Festo 8191854 is an industrial component featuring a 3-way ball valve with a pneumatic quarter-turn actuator and soft sealing principle, built on EN 10226-1 and ISO 5211 norms with an F0304 flange hole pattern. Designed for in-line installation in any mounting position with Rp3/8 fitting connections, this 3/2 valve function unit accommodates a nominal width DN of 10, a nominal pressure PN of 63, and an operating pressure range of 0.55 MPa to 0.8 MPa (5.5 bar to 8 bar, 79.75 psi to 116 psi). It handles a medium temperature range of -10 °C to 200 °C with a flow rate Kv type L of 4.5 m³/h, a breakaway torque of 13 Nm at nominal pressure, and reversible flow direction for compressed air, inert gas, water without water vapor, and neutral liquids.

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.
