The Calibration Bench PRV Micro Hammer stand has been developed for a highly precise opening pressure adjustment of the mechanical pressure relief valves in high-pressure pumps.
When adjusting the opening pressure many mechanical manufacturing tolerances play an important role by conventional methods and thus increase the scattering.
By the direct measurement of the opening pressure during the calibration process in combination with a very precise positioning manufacturing, tolerances are eliminated and an opening pressure setting with minimal tolerances is possible . The workpieces from Calibration Bench PRV Micro Hammer stand are manually inserted into the test device.
