Customer and Case Study Overview	Products and Services
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.

Results

Value

Value1

Preventing sudden equipment shutdown

Collecting diagnostic data and monitoring trends during plant operation helps to prevent the deterioration of control valves, which was previously difficult to detect, and their sudden failure, which can cause unplanned shutdowns.

Value2

Optimizing maintenance plans (to TBM + CBM)*

With proper diagnosis of valve operating condition, the selection of valves to overhaul can be optimized.
* Time-based maintenance + condition-based maintenance

Value3

Faster equipment startup after periodic maintenance

Labor-intensive testing after periodic maintenance can be streamlined to accelerate equipment startup.

Diagnostic possibilities with the Smart Valve Positioners 700 Series

Adding to the functionality of the previous valve positioners (the 300 Series), Smart Valve Positioners 700 Series can also measure the motion of the control valve from different angles using built-in air pressure sensors. That allows diagnosis of underperformance and establishment of operational benchmarks before valves start working abnormally.
