Imported pressure reducing valve installation method:
1. Italy OR import pressure reducing valve can be installed horizontally or vertically on the flat pipe;
2. The installation of the inlet pressure reducing valve must be consistent with the direction of fluid flow in accordance with the direction of the arrow on the valve body. If the water quality is not clean and contains some impurities, the filter must be installed at the upstream inlet of the water pressure reducing valve;
3. Open the inlet pressure reducing valve to adjust the outlet pressure, use a one-word screwdriver to adjust, clockwise to rotate the screwdriver outlet pressure becomes larger, and vice versa, the outlet pressure is reduced, adjust with the pressure gauge until the outlet pressure reaches the required value;
4. The imported pressure reducing valve plays a certain role in the pipeline. In order to prevent the damage of the water hammer, a small expansion tank can also be installed to prevent damage to the pipeline and the valve. The filter must be installed in the inlet pipe of the inlet pressure reducing valve. Before, the expansion tank must be installed after the water relief valve outlet pipe;
5. If it is necessary to install the inlet pressure reducing valve in the hot water system, a check valve must be installed between the water pressure reducing valve and the expansion water tank. In this way, the expansion tank can absorb the volume of water increased due to thermal expansion, and can prevent the influence of hot water return or pressure fluctuation on the water pressure reducing valve, and ensure the long-term normal operation of the Italian OR inlet pressure reducing valve.
