Functions and features:

·The control element adopts servo motor and imported torque sensor to control the opening and closing of the valve, with small inertial impact and stable control;

·Using a computer to control the test process, real-time display of pressure-time curve, test pressure and other values, test results can be automatically saved or printed out, and the test results can be automatically saved after power off;

·Computer data acquisition and processing, print out environment/medium temperature, cycle times and cycle pressure waveform;

·The opening and closing torque stroke of the cylinder valve can be set;

·The number of operating cycles can be set freely during the test, and the test can be automatically stopped when the requirements are met;

·With power failure protection function, the system will automatically relieve pressure after power failure and terminate the test to ensure the safety of operators and equipment to the limit;

·The test piece leakage can be set as the alarm point. When the leakage reaches a certain level, the system will automatically alarm and stop working, and the computer will remain powered.
