◆It is suitable to have a performance test for safety valve;
◆Test medium is nitrogen gas or air( gas source is supplied by customer);
◆High pressure air fill in the cavity of safety valve through manual relief valve, you can get accurate set pressure byadjusting relief valve slowly;
◆We advise you to choose “touch screen computer monitoring system”, the system record testing process in digitaland image curve, can be more accurately capture set pressure value and print out testing statement as technicaldocument archive;
◆We advise you to choose “safety door” to make sure safety during air seal test process;
◆Equipped automatic oil pressure discharge system, when being ready state, system discharge automatically, whenworking, system return to normal status to effectively reduce oil temperature, elongate life of the test bench andsave energy;
◆Hydraulic clamping has safety interlock with water pressure discharge;
◆Customer can choose the functions as followed:Safety door ; Touch screen computer monitoring system.
