The ValveTester is designed to diagnose and measure the operating parameters of the solenoid valves for fuel equipment control (for example, CommonRail injectors, unit injectors and sections). The ValveTester allows you to tune the control solenoid to ensure that the control solenoid operates in the same way for all engine cylinders (to ensure smooth engine operation).

The operating parameters of the control solenoid valve are among the basic parameters (along with the hydraulic parameters of the metering device and the compression value in the cylinders) and directly affect the uniformity of fuel delivery and the uniformity of engine rotation.
