Large seawater lagoons and lido systems now possible with the minimum of filtration when ACO, NoPhos and APF products are used to treat the water.   Perfotmance factor of public swimming pool systems reduced to less than 2 giving an 80% to 90% reduction in chlorine consumption.

Besgo automatic valves

pdf data sheet | buy or view prices

 
The Besgo valve is an air pressure activated multiport valve for pressure sand filters.  The valve replaces motorised multiport valves of automatic valve manifolds.  The valve comprises of a vertical pipe containing spring loaded pistons that are activated when air pressure is applied.
 
Why you should you change to Besgo
 
  • 1. simple design giving outstanding reliability
  • 2. lower cost and much simpler to install than a valve manifold
  • 3. multiport rotary valves restrict water flow, increase back pressure and make the pumps burn more energy, the besgo valve does not restrict water flow and saves energy. Example a 2" valve will save approx 0.3kw/hrs at 0.12 pounds UK per kw/hr this equates with 350 pounds per year
  • 4. the low  pressure droop also means the media can be pack-washed more efficiently
  • 5. valve fails safe in the event of a power failure
  • 6. space saving,  the valve is easy to fit in tight spaces
