Unloading Relief Valves

Port size 03 and 06 are available.
.to adjust the pressure, loosen the lock nut and turn the pressure adjustment handle slowly clockwise for higher pressures or anti-clockwise for lower pressure. After adjustments, do not forget to tighten the lock nut.
2. Take care not to neglect connecting the drain pipe to the tank; otherwise not only will the valve fail to operate properly but also the line pressure will rise infinitely. Extend the end of the drain pipe into fluid.
3 .limit the pressure drop between the valve and the accumulator in an accumulator circuit below 10% of the cut-out pressure.
4. Limit the drain pot back pressure below 2% of the cut-out pressure.
