Low pressure result in low velocity region for RNG-ke?

I have ran a SimpleFOAM RAS -RNG- K-e model of a ball vale at a small % opening position, as an axi symmetric model.
At the moment I have using PCG with a preconditioner of GAMG for the pressure calculations in fv schemes:
for K U and epsilon
My relaxation factors are:
My result has an extremely low pressure region in area of low velocity. I feel as though this is not correct and am not sure what to do to optimize the model and get a better result. I have tried adjusting delta T and write time in controldict. I can get pressure residuals to converge but still have the same result
