You can’t replace or remove it.
What’s the best way to replace a pressure relief valve?

Pressure reduction valves are used to limit the hydraulic pressure in a system. However, instead of reducing inlet pressure, they reduce the outlet pressure. It divides a hydraulic system into different sub-systems. For Example, If a hydraulic system there are numbers of operations and each has its own capacity.
How to replace a high pressure safety valve?
Step 4: Drain the engine oil. Drain the engine oil and replace the drain plug now so it doesn’t get lost. Remove the engine oil filter. Once the work is done, you will add new oil and a new filter. Step 5: Gain access to the pressure relief valve.
