Hello, I need to install a valve for the hydraulic oil cooling system on a 3cx. The valve in question is 25/905800 valve check in line, no longer available. I can not find other data of check valve, how many psi is calibrated?
The check valve is normally before the hyd return filter and is around 5 bar to give a bit of back pressure to loader and and excavator valve blocks to stop cavitation.
Thanks jcb jeff, this valve is mounted on the return steering circuit to the tank. in the photo position 19.
This will help stop cavitation in the steer circuit then.
