Trevitest™ The Original On-Line Valve Testing System– Improving Your Plant’s Uptime, Output and Bottom Line

A critical component in maintaining plant productivity, safety and profitability is to ensure that every valve is operating at peak efficiency while meeting relevant safety requirements.

With the Trevitest™ system Furmanite has the ability to test relief valves and identify those in need of adjustment or full service with no operational interruptions. This technology gives you the means to accurately test every valve, performed in place, on line and under normal operating conditions. The result is a certifiable test allowing correctly performing valves to remain in service for longer periods, as well as fully documenting valves that do not meet the correct performance criteria by our experienced personnel so that they can be repaired or replaced as soon as possible.

Exclusive to Furmanite and Adaptable to Nearly Any Job

In addition to its ability to keep your systems up and operational, even during the testing process, what sets Trevitest™ apart from any other diagnostic equipment is the ability  to be adapted to nearly any valve. This is because Trevitest™ is exclusively designed, built and maintained by Furmanite.
Our time served Trevitest technicians and our in house engineering & manufacturing capabilities mean that just because a valve cannot be tested by our current system, it doesn’t necessarily mean that we can’t create a tailored approach to make it happen!

The capability to measure several different readings simultaneously, such as spindle deflection (lift potentiometer), valve discharge and leakage (acoustic detection), inlet pressure (pressure transducer) and the spring relaxation force (load cell) offers a system that our technicians to select critical measurements of force and line pressure with amazing precision and accuracy.

With Trevitest, you have a service that has proven itself over more than 3 decades of use, and is notably more powerful and adaptable than anything else available on the market.

Turnkey Project Management & Integration

Furmanite can offer Trevitest™ as part of several services to help solve more complex customer requests. We have a long standing and proven track record in the management of high profile turnkey projects, removing the worry of managing your valves internally.
We can ensure that the right combination of valve repair, (both Shop and Field), Trevitest™, VFT (Valve Freeing Technology) and any of our other core service lines are integrated and automatically applied in order to solve your valve concerns for the most competitive price, while keeping your system’s efficiency high. Simply tell us about any problems at your plant and then let us do the rest!

Data Collection and Feasibility

We pride ourselves in offering a safe, honest and knowledgeable service. This is why we will not Trevitest™ any valve until ensuring that the right information is collected and analyzed.

Furmanite can offer detailed documentation tocustomers wanting to collect the information themselves, or alternatively, we can send suitably trained personnel to your site to analyze the requested scope and suggest the best method of undertaking the work.


Trevitest™ has built up a considerable toolbox of unique add-ons that can be applied to certain jobs when needed. These include but are not limited to:

  • Hazardous Area Module- Allows Trevitesting to be undertaken in Intrinsically Safe Zones
  • Heavy Lifting Rig- Allows Trevitest™ to exert and accurately measure over 10 tons of lifting force on a valve if required
  • Cable and Hose Extension kit- Allows Trevitest™ to be undertaken up to 100 meters away from the measurement and control equipment
  • Using Trevitest as a data acquisition system the  measurement of  the set point of pilot operated valves can be recorded  in a similar manner (requires nitrogen gas supply)
  • Torsion Bar Kit- Allows Trevitest™ to operate on torsion bar design valves.
  • Harsh environment printer kit- Ensures that no matter where in the world, a hard copy certificate can always be made available (requires minimum 9vDC power supply to operate)
