Page 30: Integral Overflow Valve
DMX model 226 en Integral Overflow Valve 8.1 Function The integral overflow valve (option) protects the complete pressure side of the dosing line system from an impermissibly high buildup of pressure. The valve opens if the pressure rises above its set opening pressure, and the dosing medium can return to the solution tank. -
Page 31: Setting Of Opening Pressure
DMX model 226 en 8.4 Setting of Opening Pressure 8.4.1 General The opening pressure can only be set if a manometer is installed in the system between the pump and the next shut-off valve or pressure retention valve. WARNING Settings on the overflow valve must only be carried out by authorized specialists! The opening pressure of the overflow valve is set in the factory to the maximum pump back-pressure specified in the technical data. -
Page 32: Venting
DMX model 226 en 8.5 Venting The overflow valve can also be opened manually, thus serving as a venting valve at the same time. If manual venting is required (e.g. when commissioning or when the tank has been replaced): Rotate the knob such that the smaller cut-out rests on the nub of the dosing head (the rotary knob is then further away from the dosing head, the valve spring is unloaded (position B). -
