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.
In contrast to series-connected overflow valves, the integral valve also provides
pump protection if the pressure valve is contaminated or blocked.
