The type of test depends on the valve and the application, among the most common are:

Body testing

Pressure applied inside the valve body

Backseat test

Pressure applied inside the valve body with backseat test

Test with valve fully open or fully closed
 

Safety valve test

Opening pressure using the "POP" test system

Leak test at 90-95% of the opening pressure
 

Special Tests

Tests with Nitrogen

Fatigue Testing

Cycle Testing with Actuators

Subsea Requirement Tests
 

Sealing test for high and low pressure

Pressure applied to each side of the closed valve

The high pressure test is performed with a pressure 1.1 times or more of the maximum working pressure

The low pressure test is performed with a pressure of 5 to 7 bar of compressed air, detected by air bubbles of a water column
