1pressure reducing valveInstallation must strictly follow the direction of the arrow on the valve body to maintain fluid flowpressure reducing valveTowards consistency. If the water quality is not clean and contains some impurities, a filter must be installed at the upstream inlet of the pressure reducing valve
　　
2. For the convenience of operation and maintenance,pressure reducing valveGenerally installed upright on horizontal pipelines.
　　
3. To prevent overpressure behind the valve, a valve should be installed at a distance of no less than 4M from the valve outletpressure reducing valve.
　　
4. If necessarypressure reducing valveWhen installing in a hot water system, you must install a check valve between the pressure reducing valve and the expansion tank. This not only allows the expansion tank to absorb the increased volume of water due to thermal expansion, but also prevents the backflow of hot water or pressure fluctuationspressure reducing valveEnsure the long-term normal operation of the pressure reducing valve.
　　
5pressure reducing valveIt plays a certain check role in the pipeline. In order to prevent the harm of water hammer, a small expansion tank can also be installed to prevent damage to the pipeline and valves. The filter must be installed in front of the inlet pipe of the pressure reducing valve, and the expansion tank must be installed after the outlet pipe of the pressure reducing valve!
