The PRV Micro Hammer setting stand was developed for precise setting of the opening pressure of mechanical pressure relief valves in high-pressure fuel pumps (GHP).
When setting the opening pressure using conventional methods, many mechanical manufacturing tolerances play a significant role and therefore increase the scatter.
By directly measuring the opening pressure during calibration, this machine can eliminate manufacturing tolerances and, in combination with a very precise positioning drive, realise an opening pressure setting with minimum tolerances.
The workpieces are manually inserted into the test device.
Highlights
- High-precision opening pressure adjustment
