1. Pilot operated pressure relief valve installed in the pipe network, you should pay attention to the direction of the water flow and the body of the arrow.
2. Pilot operated pressure relief valve in the valve must be installed before the filter to prevent dirt into the valve and affect the effect of static pressure.
3. Valve before the valve to be installed in order to repair.
4. Valve opening degree of 1/4 ring, control valve in the fully open position.
5. Initial operation when before the pressure reducing valve gate valves should be slow to open slowly, not in one fell swoop open. If decompression is not found, the valve before the valve closed, after the water is discharged, then slowly from the inlet water can decompression.
6. Adjust the pressure in static state, the valve valve in closed state. The pilot valve adjusting screw Shun clockwise rotation valve after the pressure increase inverse clockwise rotating the valve after the pressure is reduced, a good tune pressure required to the nut solid. If voltage exceeds the required pressure value, the valve after the pressure reduction, re by low upwards.
7. In the operation of such as hunting vibration phenomenon (periodic open or closed), should be clockwise and then slightly off small needle valve, the lower the closure mouth closing speed, eliminate the phenomenon of "hunting".
