Pressure reducing valve for water

Is a straight pipe part required before and after the pressure reducing valve?

The straight pipes before and after the pressure reducing valve are provided for the purpose of reducing the turbulent flow of fluid that has passed through the valve, etc., but if it cannot be installed due to the dimensions of the buried pit, etc., pressure control by the pressure reducing valve is possible without installing it.
