This valve is used to regulate the pressure of the pump's forked fluid line.
It maintains the pressure which is persistent and lower than the fluid origin not to affect the main fluid line.
There is relief valve function reverse.
This valve is a normal open type.
The spool's flow regulation or close maintains the main system's pressure.
The fluid floating causes the pilot pressure to generate pressure difference (port 2 to port 1) and then causes the unbalanced pressure of the two sides of the spool.
The spool flow changes from big to small or closes to reduce the pressure.
If the fluid on the pressure reduced side reverses (port 1 to port 2), like the cylinder is pushed back by out coming force, this valve would be like a relief valve to let the hydraulic fluid flow back to the tank and the line of the reverse flow must be drained by pilot pressure and relief pressure.
