Pressure safety valves are installed on process equipment to release excess pressure due to faulty process operations, external fires and other hazards. Or simply said; the safety valve serves to protect life and property. Failure of pressure safety valves to function properly 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 provide this important protection.
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 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.
