Hi guys,
Having a problem with Stal S24 machine which has split it's oil filter several times.
Wanting to know if anyone else has experienced this before with a poor batch of filters.
Filters are genuine part.
Press diff feed oil circuit which does not increase over time and split, seems to just split randomly.
Machine is running as a high stage machine. 2 bar Suct Press, 11 bar Discharge.
I'm also suspect of discharge check valve could be part of the problem as it is passing slightly.
How can this affect the filter on start up as it feeds to an intermediate press to the rotors and when check valve is not passing oil press diff is straight up to press within 1-2 seconds of start up???

Mainly want to clarify if it's a poor batch of filters or relative to check valve.
Heard from some other engineers that the Stal oil filters used to be an all metal gauze filter media but these filters are cardboard.
Would appreciate any help or suggestions if people have come across these issues before.

Cheers,
