Pressures The Aqualisa bar valve is designed to control static pressure up to 10 bar. Where pressures are likely to exceed 5 bar, a pressure reducing valve (PRV) must be fitted into the incoming mains supply. A setting of 3 bar is recommended. It should be noted that daytime pressures approaching 8 bar can rise above the stated maximum overnight.
A pump must only be used to boost the pressure from tank-fed supplies. A typical layout is shown on page 6. A minimum 1.5 bar twin ended booster pump may be fitted with the Aqualisa bar valve product. If fitting a booster pump, we recommend a twin ended booster pump larger than 1 bar is used.
