Daikin Industries, Ltd., Kashima Plant

The Daikin Industries Kashima Plant, which produces fluorochemical products for a industry, has recently focused on effective maintenance of control valves. The failure of a control valve has a greater impact on production than the failure of other instrumentation equipment used in plant operations, and control valves require large repair costs even in the course of regular maintenance. By switching from periodic maintenance to condition-based maintenance of these valves, the Kashima plant has significantly reduced maintenance costs and has established a system for quick handling of minor malfunctions and warning signs of future problems.
