According to Justin Mirto of Dual Valves Australasia this was DUAL’s largest unit to date on this particular model, and featured natural rubber replaceable sleeves, 316 stainless steel blade & spindle, lockout brackets and flushing ports on the underside. The unit was fitted with a double acting hydraulic cylinder per the client’s specifications and was closed gate tested to a maximum pressure rating of 4.5 Bar, and body tested to 7 Bar. Previously the largest units available were 1200NB, but the range of sizes is being expanded to meet increasing customer demand for bigger units.
“The successful design and completion of this 1500NB unit further illustrates just how far DUAL have progressed the range of options available to users of push-through sleeved type gates and other slurry handling valves. Both wafer and flanged versions of DUAL’s slurry gate valves are available in a complete range of materials of construction and actuation options, and with the HP model rated to 25 Bar, customers now have more choice than ever when it comes to selecting a DUAL slurry gate valve to suit their needs” explained Justin Mirto. “Our slurry gate valves are working all over the world – a growing list of North and South American, African, Australasian and European installations continue to prove that these products offer high performance and excellent value”.
