The simplest way to increase the throttle passage for CPU-547070-3A-M8510041 is to thicken the valve seat, causing the valve seat hole to grow and form a longer throttle passage. On the one hand, it can delay the sudden expansion after flow closure throttling, and transfer the damage position away from the sealing surface; On the other hand, it increases the throttling resistance, reduces the degree of pressure recovery, and weakens cavitation. Some design the valve seat hole in a stepped or wavy manner to increase resistance and weaken cavitation. This method is often used in introducing high-pressure valves into devices and improving old valves, and is also very effective.

CPU-547070-3A-M8510041 Change Flow Direction to Improve Valve Life Method

The open type flows in the open direction, and cavitation and erosion mainly act on the sealing surface, causing the root of the valve core and the sealing surface of the valve core seat to be quickly damaged; The flow closed type flows in the closed direction, and cavitation and erosion act below the sealing surface of the valve seat after throttling, protecting the sealing surface and the root of the valve core, and extending the service life. When the problem of extending the service life of valves used as flow opening type is prominent, simply changing the flow direction can extend the service life by 1-2 times.
