This multi-way diaphragm valve is designed to control high purity, sterile, aseptic, steam and CIP media. The Robolux system enables an extremely compact, space-saving design and is based on the patented Robolux 2-weir technology, where a diaphragm covers two valve weirs in one valve. Thanks to the individual design, valve combinations with minimal dead spaces can be realised in the smallest of spaces. The valve housing is machined from a stainless steel block. The valve actuator contains two independently operating actuators in a stainless steel housing and is operated with compressed air. With the special feedback indicators and control heads, the Robolux system can be perfectly integrated into the decentralized Bürkert automation concept.
