Pilot pressure relief valve installation methods
1, Pilot pressure relief valve installed in the pipe network, should pay attention to the flow direction and the body of the same arrow. 2, pilot-pressure regulator valve must be installed in front of the filter to prevent dirt into the valve and affect the static pressure effect. 3, after the valve before the valve to be installed in order to repair. 4, needle valve opening degree of 1/4, the control valve is fully open position. 5, the initial operation, the valve in front of the valve should be slowly slowly opened, can not be fully open in one fell swoop. If you do not find decompression, the valve will be closed before the valve, the water after the release, and then slowly imported water, you can decompression. 6, adjust the pressure to be carried out under static pressure, that is, the valve after the gate valve is closed. The pilot valve adjustment screw clockwise, the valve pressure increases after the counterclockwise rotation of the valve to reduce the pressure, adjust the required pressure to lock the parent solid. If the pressure exceeds the required pressure value, the pressure required to reduce the valve, re-adjusted from low to high. 7. If there is "hunting vibration" (periodic opening or closing) during operation, turn the needle clockwise a little further to reduce the closing speed of the shut-off port and eliminate the hunting hunting phenomenon.
