I have a low pressure Nitrogen blanketed Demineralised Water storage tank. What is the conventional approach for high pressure / vacuum protection

1) Providing PVRV (Pressure vacuum relief valve)

OR
2) Separate Pressure safety valve & Vacuum valve

You can apply either design - as long as you provide sufficient pressure and partial vacuum capacity protection for the tank, taking into consideration ALL credible over-pressure and partial vacuum scenarios.
