Now the valve will travel from 0% to 25%. Check for leaks in the body and bonnet using a pressure gauge or leak detection equipment. Slowly close the valve and measure the pressure drop across the valve. Valve leakage test results can vary based on the technique of the tester, so it's essential to have your valves tested by trained, highly qualified technicians. If a leak is detected, repair or replace the valve. The pressure is applied inside the assembled valve with the ends closed. 2.
