The PreVenTest System enables you to test your spring operated safety valves on site without interrupting the process operation. With this so called ‘hot testing’ the safety valve stays on-line and no dismantling of the valve or plant shut-down is required.
The main advantages are:
NO PLANT SHUT-DOWN
NO DISMANTLING OF THE VALVE
NO LOSS OF PRODUCTIVITY & PROFITABILITY
During the test, a combination of accurate, calibrated sensors measure the force, lift, acoustics and (if possible) the process pressure.
The easy operated Ventil PreVenTest program directly shows the "found test data" in a clear combination of graphics and values.
The information enables the operator to accurately identify the settings of the tested safety valve.
After the valve disc has re-seated, the PreVenTest System automatically stops the test and prompts the test results in clear figures and graphics
S/W enables the operator to execute a series of 3 tests to ensure the consequent and reliable performance of the valve and accuracy of the test results. Finally the results of each individual test and an average of the 3 are shown.
From the information recorded during testing the following information can be obtained:
- Valve set pressure,
- Spring adjustment,
- Displacement of the valve,
- Re-seat pressure,
- The effect of the nozzle ring,
- The effect of the guide ring.
