Next-Generation Knife Gate Valves for Dewatered Tailings Applications

Next-Generation Knife Gate Valves for Dewatered Tailings Applications

With Clarkson KS1 knife gate valves from Emerson, the improvement was dramatic and immediate. After 8 months, the new valves remain in service, never having required a repair or change out. The installed cost of each valve was less than $27,000, so the project paid for itself in just over two weeks, and it has been generating nearly $10,000 per week in savings since.

How Electric Actuators Aid Sustainable Mining Operations

The best technology often depends upon the relative size of the valve and the existence of a compressed air system. If a pressurized air system already exists, adding a few more pneumatic valves to it is likely the best choice. In a greenfield application, an all-electric actuation solution may be better option, particularly when the capital and operational cost of a new compressed air system is considered. Other drivers impacting the decision include a requirement for variable stroke/torque profiles or precise positioning, the ability to power actuators with solar power, or water-constrained environments, which raise air compressor operating costs significantly.
