Features and benefits - The need for innovation in the world of swimming pools has led AstralPool to develop a range of automatic selector valves to replace traditional manual valves. With simple programming from the integrated programming keypad, the system will allow you to have fully automatic operation of your pool, leaving you time to enjoy it and relax. - With its innovative design, easy handling and maximum reliability, it is designed for residential pools with filters of 600 diameter maximum. - It allows you to adjust the times of the functions by means of a potentiometer and to see the position of the function that the valve is carrying out at any given moment. - Unlike the System Vrac Basic Valve, which can perform the flushing function, either by pressure difference or by time, this new model will only perform the flushing function when it detects pressure in the filter. - Drain button on the side of the actuator. - Non-programmable fixed rinse time (30""). - Product selected eco. To obtain water in optimal conditions for bathing, the filtration system must work properly on a daily basis and with the filter washes required at all times. Otherwise, the water can spoil and lose its good conditions, making bathing impossible and causing the cost of refilling the pool or its recovery with chemical products. The use of automatic selector valves allows the user to be completely unconcerned about the problem of filtering their pool and avoid unnecessary emptying of the pool, with the consequent saving of water.
