Festo
4810852
Ball valve VZBF-3/4-P1-20-D-2-F0304-V15V15
The Festo 4810852 is a mechanical 2-way ball valve featuring a soft sealing principle and an inside diameter of 20 mm with a nominal width DN of 20. This 2/2 valve function component supports a reversible flow direction, a flow rate Kv of 59 cubic meters per hour, and a nominal pressure PN of 20, operating across a medium temperature range of -20 °C to 200 °C with vapor, compressed air, inert gas, water, and neutral liquids. Featuring in-line installation with any mounting position, an ANSI B16.5 class 150 flange connection, and an F0304 flange hole pattern based on ANSI B16.5 class 150 and ISO 5211 norms, it requires a breakaway torque of 10 Nm at nominal pressure and includes RoHS compliance with VDMA24364 Zone III LABS conformity.

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.
