1. Vertically installed pressure reducing valve sets are generally installed along the wall at a suitable height from the ground; horizontally installed pressure reducing valve sets are generally installed on a permanent operating platform.
2. The applied section steel is loaded into the wall on the outside of the two control valves (usually used for shut-off valves) to form a bracket. The bypass pipe is also stuck on the bracket and leveled.
3. The pressure reducing valve should be installed upright on a horizontal pipeline, and should not be inclined. The arrow on the valve body should point to the direction of the medium flow and should not be installed backwards.
4. Stop valves and high and low pressure gauges should be installed on both sides to observe the pressure changes before and after the valve. The diameter of the pipe after the pressure reducing valve should be 2#-3# larger than the inlet pipe diameter before the valve, and a bypass pipe should be installed for maintenance.
5. The pressure equalizing pipe of the membrane pressure reducing valve should be connected to the low pressure pipeline. Low-pressure pipelines should be equipped with safety valves to ensure the safe operation of the system.
6. When used for steam decompression, a drain pipe should be installed. For piping systems that require a high degree of purification, a filter is installed before the pressure reducing valve.
7. After the installation of the pressure reducing valve group, the pressure reducing valve and safety valve shall be tested, flushed and adjusted according to the design requirements, and the adjusted mark shall be made.
8. When flushing the pressure reducing valve, close the inlet valve of the pressure reducer and open the flush valve for flushing.
