1 Hoist valve to suitable position, adjust column horizontal position of torque output device and beam position to make torque spanner claw alignment with valve hand wheel center;
2 Exhaust air in the body of valve, pressurize test media to regulated value;
3 Pre-close valve with smaller torque; open left discharge valve to empty left cavity of valve, then valve seal pressure difference is of full pressure, may be larger leakage, the system will automatically compensate test medium pressure ;
4 Move left work table, press button “oil motor torque enlarge” and observe valve leakage condition, when valve leakage meets the standard, torque value recorded in touch screen and PLC auto control system is closing torque value of this test;
5 Repeat test of closing torque value three times, choose the maximum value as valve closing torque value;
