Trevitest Hot Testing

When hot testing (a test in service under normal operating conditions) you get a date-marked and certified printout of set pressure and the line pressure at the valve. With this information, you’re able to accurately determine the set pressure, and required spring adjustment when an adjustment is required.

Hot Testing Benefits

No plant downtime required for testing

Less time is required to commission the plant after shutdown

Only valves that require an overhaul need to be removed from the line

Most spring loaded valves including welded-in valves can be tested on-line

No need for temperature compensation for set pressure

Trevitest Cold Testing (United Kingdom and Europe only)

Trevitest Cold Testing enables you to determine set pressure, spring rate and valve displacement. Cold Testing is an important component to include when pre-commissioning safety and relief valves on new plant, or when conducting workshop testing in order to give the valve a ‘fingerprint’ (immediately following the conventional bench test).

Cold Testing Benefits

Eliminates the cost of removing valves from their location prior to commissioning new plant

Only valves that require an overhaul need to be removed from the line

Correct spline alignment of torsion bar safety valves significantly reduces the risk of unplanned shutdown

Functionality Across Multiple Industries

Thermal, hydro and nuclear power generation

Offshore oil and gas production

Refineries & distribution and petrochemical plants

Fertilizer plants

Food processing plants

Pharmaceutical plants

Pulp and paper plants

Schools and Universities

Municipalities and public facilities

Trevitest Diagnostic Recorder – Improving Your Plant’s Uptime, Output and Bottom Line

A critical component in maintaining plant productivity, safety and profitability is to ensure every valve is operating at peak efficiency and meeting all safety requirements. How do you do that? Right now the only way to know if a valve is in need of adjustment is if it breaks down or to shut down the system and test each valve. Either of these options will cost you – time, productivity, money. That was then, this is now.

With the Trevitest® diagnostic recorder you now have the ability to test relief valves and identify those in need of adjustment 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.

Trevitest – The Standard in Test and Measurement

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 recorder is the capability to measure several types of phenomena when a user is testing pressure relief valves. Trevitest has the ability to measure a valve’s spindle deflection (lift potentiometer) or valve discharge (acoustic detection), as well as inlet pressure (pressure transducer). This is in addition to measuring the spring relaxation force (load cell) that has been available with previous versions.

In other words, Furmanite has engineered a state-of-the-art valve test solution that enables users to measure pressure, lift or displacement, and sound via acoustic detection. It also allows users to select critical measurements of force and line pressure with amazing precision and accuracy.

With Trevitest, not only do you have a tool that is notably more powerful and dynamic than anything else available on the market, but it is remarkably lightweight and modular in design. This considerably enhances its ability to be used under variable plant conditions, as well as to integrate with other specialty diagnostic equipment required in user-specific applications.
