Hydraulic pump question

[Garyjp]

Possibly its a pilot operated check valve for internal leakage. The leakage is used for lubrication to bearings on the low pressure side of the pump. (pilot valves uses a very small hole from the pressure side to operate a valve elsewhere on the same component)

 

The plug and valve would be reversed if the rotation is altered to suit a power source with opposite rotation.

 

Im not familiar with that specific pump. Its unlikely to be a relief valve.

Should have added that even if you remove the valve its unlikely you will know what its function is exactly without the circuit drawing of the pump! You will only ascertain if its a valve or simply a plug!
