Valve analysis and diagnosis

Specialized engineers analyze various data compiled online to assess the condition of control valves without the need for an overhaul.

Key devices employed for the analysis include the control valve maintenance support system (Valstaff), device management system (InnovativeField Organizer), and smart valve positioner (300 or 700 series).

The results are compiled into an analytical report used to discuss maintenance plans and future measures for achieving more efficient maintenance and optimized life cycle costs, including control valve upgrades.

Optimization of control valve maintenance cycle

This improvement cycle is a rearrangement of the PDCA cycle that works by bringing in the step of checking (C) at the very beginning. In contrast to a PDCA cycle, this does not involve difficult initial planning.
Rather than trying to make any improvements, the cycle begins by assessing the current condition, which makes it easier to plan any improvements in response to the current condition. In this manner, the cycle facilitates continuous and practical action to make improvements.

Valve trend management

Our specialized engineers will diagnose control valves used at your site based on their appearance and create a valve diagnosis record in order to assist with your maintenance planning.
In this way, Azbil helps you to prevent problems caused by deteriorating parts in order to maintain safety and reliability.

The service life of a control valve in a manufacturing plant depends significantly on the installation environment and process fluid.
A control valve has an actuator, moving section, and a sliding section that include limited-life parts. The product's service life is represented by a failure rate curve (a "bathtub curve").
Continued use of a control valve whose parts are beginning to experience failure from wear not only shortens the product's service life, but might cause the shutdown of your equipment.
Our valve doctors with specialized skills can visit your site and diagnose your control valves while they are in use.
