MINING & SLURRY VALVES

CORAL VALVES manufactures and distributes a wide range of Butterfly,Gate,Globe,Check,Ball and Control Valves for the Mining Industry. We cover all areas of the plant, from dilution waters, mine dewatering and a variety of valves for specialty applications such as flotation tanks and cyclones.

CORAL VALVES supply and support many mining companies through Africa.
The mining industry is traditionally a heavy user of pinch, slurry and tailings handling valves because of the highly abrasive nature of metal concentrates. We at CORAL VALVES have proven success over the years in this harsh environment in slurry and tailings applications as well as leaching processes.

CORAL VALVES extensive range of slurry, industrial, and process valves are suited to almost every application where the flow of slurry, gas, or liquid needs to be regulated. Our valves are designed for ease of maintenance and maximum reliability while operating under extreme conditions. Available actuators include manual, pneumatic, hydraulic, electric motor and bevel gear.

Our Johannesburg based workshops are capable of valve repair, pressure testing and actuation fitment and calibration. Our team offer fastest possible turnaround times to ensure minimal downtime and reduced risk of disruption during your plant’s operation.
