In the field of bulk material technology, the LINNEMANN GmbH program contains specially designed, pneumatically operated pinch valves. These are available with a variety of different process connections. The very practical ring grip pipe couplings, which enable easy and safe pipe couplings without the need to weld flanges, are also available for this field of application. The large-radius arcs and other fittings that are required for bulk handling complete the product range.
