A pressure regulating valve is (see pump capacity curves)\nused to by-pass all oil which is not required at the nozzle.\n Shaft rotation and\nOne-pipe installation nozzle location\nThe oil which does not go through the nozzle line is returned directly to the (seen from shaft end)\ngear inlet and the suction line flow is equal to the nozzle flow. In that case, the A: clockwise rotation/\n right hand nozzle.\nby-pass plug must be removed from the return port, and the return port sealed B: clockwise rotation/\nby steel plug and washer. left hand nozzle.\nTwo-pipe operation C: anti-clockwise rotation\nThe by-pass plug is fitted in the return port, which ensures that the oil by-passed left hand nozzle.\n D: anti-clockwise rotation\nby the regulating valve is returned to the tank and the suction line flow is equal right hand nozzle.\nto the gear set capacity.\n K: kerosene applications\nCut-off\n Pump series\nThe solenoid valve of the OL pump is of the \"normally closed\" type and is 1: conical thread\nsituated in the nozzle line. This design ensures extremely fast response and 4,5,6 : cylindrical thread\nthe switching can be selected according to the burner operating sequence and Model number\nis independent of motor speed.\nWhen the solenoid is : OL V 35 C K 9 1 xx 1 P 06\n- non-activated, the valve is closed and all oil pressurized by the gear set\n Revision number\npasses through the regulator to suction or the return line, depending upon\n Installation\npipe arrangement.\n P : by-pass plug inserted in return port\n- activated, oil passes to the nozzle line at the pressure set by the pressure for two-pipe operation\nregulating valve.
