FEL valvle problems dongfeng ZB25

[J_J]

There could be two P ports, and two tank ports for best mounting situations.

Can you confirm that the fitting with the 90 degree hose is a PB fitting.

Just remove the fitting and it should have two o-rings on it. Take a picture of the fitting removed from the valve. If it looks like the fitting I posted, then it is a PB adapter.

PB is a high pressure path for the fluid to progress to the next valve, and used in most situations because there is usually another valve downstream.

T ports usually go to a tank line and can be teed.

Your flow path might be something like this.

Pump to three spool valve, to remotes if you have them, and 3pt.

I can confirm the 90 fitting does not have 2 O rings. It is exactly the same as the tank fitting but with a 90 deg angle. All ports have one O ring that slot into valve side of the ports (acts more like a washer). There is only a size difference with the tank/pump ports compared to the work ports. As far as I can figure, the valve is standard on an 'East Wind' tractor (DongFeng factory). Dong Feng tractors are a poor mans poor mans tractor so probably get downgraded a bit on parts since the original valve was simpler. Apparently Dong Feng means 'east wind' anyway.
