As a control valve manufacturer, we know how to achieve safe and stable operation and optimized maintenance through state-of-the-art technology

The smart way to solve valve-related problems at production sites

• Failure is often unexpected because you can't see the conditions inside the valve.
• I want to know if a problem is developing!

Early detection of problems

Using Azbil’s Diagnosis Service enables you to catch signs of abnormality before the process is affected.

A new method of management
(trend monitoring)

• With time-based maintenance (TBM), valves that are in poor shape may be missed.
• But is condition-based maintenance (CBM) really feasible?

Optimize the selection of valves for periodic repair

If you know about valve deterioration in advance, you can overhaul valves that would not normally be selected for TBM, preventing future problems.

Use TBM + CBM

• Thanks to HART communication I have data on valve motion, but judging valve health is still quite difficult because I’m not a specialist.

Freedom to focus on critical work

Our full-time engineers analyze the data, diagnose valve health, and submit reports to you based on valve operating data, fluid and valve type, and the conditions of use. This frees you to focus on the work you need to do.

Valve Diagnostics Service solutions

• Since we put so much time and effort into pre-startup inspections after periodic repair, starting up the equipment seems to take forever.

Streamline post-maintenance testing

We streamline various labor-intensive tests after periodic maintenance, so your equipment is back up and running quickly.

Streamline pre-startup inspections

Highly reliable service,
applying a valve manufacturer’s wealth of experience

We do the work of analyzing and diagnosing valve health for you,
in support of optimal valve maintenance planning.

By reducing the time and effort needed to use diagnostic tools, analyze the data, and make diagnoses, we free you to focus on maintenance work and help you to streamline work the smart way.

Support for
a wide range of valves

Diagnosis of 7 valve types: globe, double-seated, cage, diaphragm, eccentric rotary, butterfly, and ball.

Diagnosis of
diverse phenomena

By analyzing combinations of various types of operating data, we can identify a wide range of phenomena.

Three types of diagnostic
service for different purposes

We offer three types of diagnostic service: primary screening, detailed diagnosis, and comparative verification, each optimized for your objectives.

Diagnosed cases

Utilizing the Valve Diagnostics Service, you receive diagnoses of various phenomena so that you can prevent trouble.

Device abnormality found

Something abnormal was detected in a loop that seemed OK according to the control results, and a potential problem was prevented.

Valve clogging found

A problem was found in a valve that may have been excluded from TBM, improving the selection of valves to repair.

Customers and results

We are making an increasing number of diagnoses for many types of valves at a wide range of plants.
