ECO GREEN automatic bypass
The automatic proportional bypass accessory enhances the system with following
functions when fitted upstream of the water treatment system:
• Supply of untreated water during regeneration cycle 4C. In this cycle, the valve does not provide
hard water bypass during the regeneration.
• If there is a temporary increase in the water consumption, the pressure drop inside the valve
and through the resin bed increases substantially. In this case, due to the differential pressure
that has been created on the inlet and outlet sides of the bypass, the automatic bypass valve
opens to balance the outlet pressure with the inlet pressure, ensuring a higher flow rate at the
outlet. But, of course, in that case, an intermediate hardness is obtained during part of the service
cycle.
• Disconnection of the valve or the entire water treatment system without causing a break in the
supply of water. In this case, only untreated water is available for the user.
