A non-return valve (NRV) is placed before a hand valve to prevent backflow in the system. This ensures that fluid only flows in one direction, protecting the system from potential damage or contamination caused by reverse flow. Additionally, it helps maintain pressure and system integrity, allowing the hand valve to operate effectively without the risk of fluid returning when closed.
