Burkert Robolux multiport valves

Robolux multiport valves are designed for clean and washdown areas, and can be combined with Burkert’s Element control heads to provide decentralised automation of hygienic processes.

Based on diaphragm valve technology, the design of the valves combines independent dual switching functions in a single body, with single diaphragm and actuator. The compact design occupies approximately 50% less space than traditional valve manifolds, and is more easily sterilised. Low internal volume and elimination of dead leg supports faster cleaning and a higher product yield, with the compact construction also streamlining installation and maintenance.

The combination of the multiport valves with Element control heads is claimed to present new possibilities for the decentralised automation of hygienic processes. The integration of all automation functions within the control heads allows the valves to be equipped at field level with required automation components, including pilot valves, electrical feedback units and optical status indicators. The control heads also integrate optional fieldbus interfaces, allowing up to 62 valves to be connected to a PLC in series by a single 2-wire line.

Typical applications are found in hygienic food and beverage, pharmaceutical and biotechnology processes. Manufacturing applications where dosing chemicals carry a high per-unit cost are also indicated. The valves are said to support such applications with high reliability and repeatability, with an internal and external design that supports purity and sterile process conditions.
