Festo
8191905
Ball valve unit VZBE-A-4-T-63-T-2-F1012-V15V16-PA240
The Festo part number 8191905 is an industrial 2-way pneumatic soft-sealed ball valve with a quarter turn actuator configured for in-line installation in any mounting position. It features a 4 NPT fitting connection, a nominal width DN of 100, a 2/2 valve function, and a nominal pressure PN of 63 based on ASME B1.20.1 and ISO 5211 norms with an F1012 flange hole pattern. The unit operates at a pressure range of 0.55 MPa to 0.8 MPa (5.5 bar to 8 bar or 79.75 psi to 116 psi) with a breakaway torque of 138 Nm at differential and nominal pressure, accommodating a flow rate Kv of 1637 m³/h across a medium temperature range of -10 °C to 200 °C. Compatible media include compressed air as per ISO 8573-1:2010 [-:-:-], inert gas, water without water vapor, neutral liquids, and other flow media on request.
