Pressure Relief Valve Function

When output pressure of rough pump is higher than 46MPa,the relief valve opens to release the pressure and protect pumps and valves.

Maintenance and trouble shooting

Open pressure is too high or too low
1)Setting pressure is not suitable,adjust the pressure again
2)The spring is burnout,change a new one.
3)Dirty things block the valve sealing line,remove the fluid inlet body to clean the dirty things and reinstall again.
