一、Application

PR2 Test System is designed and manufactured as one comprehensive type of testing equipment as per API SPEC 6A, GB/T22513, and other related industrial standards, which is capable of carrying out the PR2 level tests for valves, showing as followings: hydrostatic test, gas leakage test, open or operating torque test, open/close cycling dynamic test at room temperature, open/close cycling dynamic gas pressure test at maximum/minimum environmental temperature and valve pressure/temperature cycle testing.

二、System Combination

PR2 test equipment mainly consists of 3 sections, i.e.: Temperature Control System, Torque Control System and PC Control System. Therein, temperature control system is used to create high and low environmental testing temperature; the torque control system is used to control the open/close operations of valves and torque measurement; the PC control system is employed for automatic control of the testing process, acquisition and storage of test data and test reports.
