Product Description

This is a heavy duty Adjustable Spring Loaded Pressure Relief Valve for safety protection of your irrigation system that can be adjust from approximately 20 - 100 PSI. Unit is constructed of all metal components, except seals. These spring loaded valves are set so when excessive pressure develops in a piping system the spring valve pops open, allowing release of pressure, thus decreasing pressure within the system. These are not precise valves, their function is as a safety measure only, so having a precise relief setting is usually not necessary. The important part is that the valve “pops” before any damage is caused to your system. This type of valve does not control the operating pressure in a system. 

Tightening down (clockwise/right) the nut increases the relief pressure, loosening (counter-clockwise/left) the nut lowers the relief pressure.  It is possible to have it too loose where the system will leak under minimal pressure. The best way to set it to a close PSI rating is to tension the nuts in about 1/5 intervals (1/5 down equals approx. 20 PSI) and then use a pressure gauge with the port on the side to see where the valve is releasing. The factory setting is suppose to be 60 PSI or about 3/5 down, however please check at installation to assure setting is as close as possible to your preferred pressure range.
