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.

尾矿需要有效的管理,运营才具有成本效益。虽然尾矿风险不太可能影响实际开采工作,但倘若尾矿坝倒塌,可能会破坏矿场的价值,有损公司声誉并影响经营许可证。无线尾矿坝监测有助于管理风险并增强安全性。
阀门在尾矿运输和确定尾矿分布情况中发挥着至关重要的作用。由于尾矿是粗颗粒物质,并且往往具有腐蚀性,因此尾矿输送管道中使用的泥浆阀必须能够承受泥浆中不断变化的固体含量,并且长时间保持正常运行状态。当增加压力、密度和速度时,尾矿运输意味着阀门运行的环境十分严酷,而许多尾矿池位置偏远,维护不便,因此可靠性和低维护需求极为关键。
