Advantages
- Essential when working with flangeless valves (allows testing of spring operated safety valve directly on their operational pipeline position without plant shut-down).
- High accuracy of test results due to use of four interchangeable pressure sensors with accuracy class of 0.25% (with ranges of 16, 40, 100 and 250 Bar) as well as two interchangeable force sensors with class of accuracy 0.03% (with ranges of 2; 20; 50 kN).
- Small device weight makes it convenient to move across the plant.
- Does not require connection to any sources of energy during testing.
- Universal mounting bracket simplify installation of the unit.
- Allows testing of Pressure Safety Valves on the pipeline under pressure and without it.
- ATEX certificate allows to use it in hazardous areas.
- Acoustic sensor allows to determine set point precisely
- Emergency valve closing system.
