Clyde Materials Handling has received an order for a further four 200mm Dome Valves from a supplier of vertical shaft kilns. Two will operate against a 16barg pressure and two against 7barg. The Dome Valves are required to fulfil an order from a Chinese company involved in the extraction of sulphur from petroleum coke. The Dome Valves will be used in the lock hopper system that feeds the petroleum coke into the kiln. Other orders from the same company to follow are for Honduras and Brazil.
