ASTRAL VRAC BASIC automatic multiway valve
Astral VRAC BASIC automatic multiway valve 1''1/2 Var.3
replaces 6-way valve, with diameter 50 or 63
They are equipped with a VRAC system which adapts to all ASTRAL filters.
The range of SYSTEM VRAC BASIC valves are available in two lateral standard measurements : 1''1/2 and 2''.
In order to obtain quality pool water, avoid cloudiness and the development of bacteria, the pool filtering system must be used on an adequate everyday basis. Failing this, serious consequences could arise, even resulting in not being able to use the pool. In this case, a total pool purge with heavy chemical treatment may be required.
Providing a regular and automated treatment, the VRAC BASIC from ASTRAL allows you to forget the constraints linked to pool filtering. This avoids debris and dirt remaining present in the pool hydraulic circuit and obstructing your sand filter, guaranteeing perfect water quality.
Filtration is facilitated, you have no need to manipulate your valve.
By simple programming of your digital keyboard, your filtration system is totally automated.
FiltrationThe operational times of filtration are defined by an external timer situated in the pools electrical cabinet. The valve can equally be operated whenever you wish by using the forced-operated mode.
Back washIf the filter is clogged, the circulation of water becomes more difficult and pressure builds up. When the pressure reaches a limit which is predefined by the user, the backwash will begin automatically via a signal sent from the pressure switch.
You can also program a weekly backwash cycle, even if the pressure level has not been reached.
RinseIs completed automatically after backwash.
EmptyingEffectuated via a push button positioned on the valve that is confirmed via the electrical cabinet. This avoids an unplanned purge as the button must be held for 3 seconds.
The difference between the SYSTEM VRAC FLAT which is only operational when pressure is detected in the filter and the new model VRAC BASIC which is capable of automation either by detecting pressure change, either by programming.
