Cleanliness

The maximum allowable cleanliness of the oil should be according to 9th degree of Standard NAS1638.lt is suggested that the minimum filter rating should be β10≥75。

Check valve allows the fluid to flow only in one direction and prevents it from flowing in the opposite direction.
Check valve could be used at the outlet of hydraulic pressure pump to avoid the oil flow backwards. It can also separate the oil lines to avoid the oil lines mutual interference.
It can be used as by-pass valve.
