Advantages: Extend the service life of the equipment and save water for unnecessary operations. It is used to reduce the pressure above the system limit. The user first needs to know the design pressure through hydraulic calculation, and other areas also need to be hydraulically calculated. Thereafter, fire pump selection and pressure adjustment are performed based on the calculated maximum design pressure. The pressure gauge should be used before and after the pressure reducing valve. If the relief valve outlet pressure is greater than 1/2 of the design pressure, a safety valve should be used. However, the safety valve set pressure value of 12.1 bar must not be exceeded.
