The hydraulic cylinder top pressure valve test bench is a universal, efficient, and powerful valve testing equipment. The core design concept is to use the axial thrust generated by the hydraulic cylinder to directly drive the end face sealing pressure plate or blind plate, and to compress and seal the tested valve between its end flanges, thereby conducting the valve’s shell strength test and sealing performance test. This device has become the mainstream choice for product quality inspection and certification in valve manufacturing, pressure vessels, and various industrial fields due to its strong clamping force, wide applicability, and excellent sealing effect.

Made of high-strength box beams or high-quality thick steel plates welded together, the structure is stable and can withstand the huge pushing force of the oil cylinder and the high-pressure reaction force generated during testing, ensuring long-term use without deformation.

Usually a horizontal structure, providing open operating space

Technical performance and feature

◆Top cylinder valve test bench is suitable to have a test for various connection types of valves, we advise you equip”servo control system”

◆Top screw valve test bench is suitable to have a test for inner tunnel sealing valves, if a user selects plane orwelded groove sealing valves, you need to choose bootstrap tank system;

◆Test medium is water or air(6 bar gas source supplied by customer,test medium water can be recycling), can bechanged over by pipeline control valve;

◆Equipped LP water filling、 HP water filling and pressure-keeping & timing auto-control system;

◆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 pressing device (top screw) has safety interlock with water pressure discharge;

◆Customer can choose the functions as followed: Touch screen computer monitoring system;Servo controlsystem; Bootstrap tank system.
