GCC offers robust FEDUR valves containing wear resistant lock plates. These plates regulate the flow in abrasive slurry transports. Our in-house engineering provides a seamless slurry passage through the Fedur valve housing in the pipe system. The durable valves are used, among others, in slurry regulating loading systems (hoppers) and in bulk load and unloading systems. The valve has a very long life. This applies, in particular, to the service life of the regulating valve for regulated flow control.
