Installation instructions and precautions of pressure reducing valve

1.It is not recommended to use thread sealant or liquid raw material tape for NPT thread installation. Improper operation will easily cause liquid to flow to the filter element in the valve and cause the filter element to be blocked. Finally, there is no pressure at the valve outlet or the flow is too low	2.The filter must be installed upstream of the pressure reducing valve, otherwise the system particles will damage the valve seat,resulting in internal leakage of the pressure regulator, downstream pressure rise, and easy damage to the outlet pressure gauge or other equipment. It is recommended to use a filter element with a precision of not less than 20 microns	3.Before installing the pressure reducing valve, the pipeline must be cleaned, and the gas should be used for continuous purging to thoroughly clear the magazines and particles such as iron filings when cutting the pipeline;

4.In the flow state, turn the handle clockwise to increase the outlet pressure and counterclockwise to decrease the outlet pressure. When the outlet pressure is reduced to zero, the handle of the pressure reducing valve should be in a loose state. Excessive counterclockwise rotation of the handle may cause the thread to get stuck, or the handle is loose and cannot be adjusted again

5.It is not recommended to use the pressure reducing valve as a stop valve for a long time, otherwise the valve seat may be deformed, resulting in unstable flow

6.Handle with care to avoid any impact, especially the pressure reducing valve with pressure gauge. The pressure gauge is a sensitive element and may be damaged by external force
