2. The piping system must be flushed before installing the pressure reducing valve. In order to prevent the welding slag, oxide scale and other sputum from flowing into the valve, affecting the normal operation of the valve. The valve should be installed in a place that is easy to operate and maintain, and must be installed upright on a horizontal pipe. Care should be taken to make the flow direction of the medium in the pipe consistent with the direction indicated by the arrow on the valve body. Do not reverse the installation.
3. When the pilot steam pressure reducing valve is installed and used, the shut-off valve of the bypass pipe should be opened to eliminate the mixture of condensed water and soda water in the pipeline to prevent the garbage valve from being damaged when the pressure reducing valve is opened. When there is no abnormality, slowly rotate the adjusting screw clockwise to adjust the outlet pressure to the required pressure (according to the valve back pressure). After adjustment, tighten the lock nut and tighten the protective cover.
4. Install a filter before the stainless steel steam pressure reducing valve to prevent debris in the medium from entering the pressure reducing valve and affect its performance.
5. There should be a straight pipe before and after the installed pressure reducing valve. The length of the straight pipe in front of the valve is about 600 mm, and the length of the straight pipe behind the valve is about 1 mm. Generally, the pressure reducing valve requires that the inlet and outlet pressure difference must be ≥0.2Mpa.
6. Pressure reducing valves usually have various specifications such as DN50~DN100. The working pressures before and after the valve are <1MPa and 0.1~0.5MPa respectively, and the error of the pressure regulating range is ±5%~10%. It should be noted that steam has a large loss through the pressure reducing valve, but it is still energy-saving in general due to the reduction of steam waste and reasonable distribution of system flow, improved system layout and working conditions.
