Online test system for Safety Valves Pressure safety valves are installed on process equipment to release excess pressure due to faulty process opera- tions, external fires and other hazards. Or simply said; the safety valve serves to protect life and property. Failure of pressure safety valves to function prop- erly could result in the serious damage of vessels, exchangers, boilers, or other equipment. It is essential to maintain pressure safety valves and relief valves in good condition, periodic testing is one of the most important elements to ensure that the safety valves will pro- vide this important protection. In-Situ Testing light weight & battery operated IN-SITU TESTING Obviously, the most desirable type of test is one that subjects the pressure relief valve to the full operating conditions that it is to endure in practice. The PreVenTest LTC system enables the testing of 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. VENTIL, INNDVATDRS IN VALVE TESTING Ventil Test Equipment B.V.

HOW DOES IT WORK..? The PreVenTest system is a robust, but ingeniously build test system, comprising of a universal test bracket and intelligent hardware & software. The light weight ‘airplane’ Aluminium test bracket is easily adapted to the valve size and is quickly positioned and connected to the valve. After you have entered or selected the valve and process circumstances, the program automatically selects and recommends the correct and most accurate configuration of the bracket and sensors. The valve data can be manually entered new or taken from the valve management database. The...

GRAPH ANALYSES After the valve disc has re-seated, the PreVenTest system automatically prompts the test results in clear figures and graphics. The easy operated program enables you to zoom in to graphs and carefully analyse the found values and determine the critical points. After the test the found test results are automatically stored in the database and are available for future reference. The PreVenTest program 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...
