Control of air in water systems is as essential as control of water. The major benefits of using air valves are increased system efficiency and shorten filling time, saving of energy as well as protection from vacuum conditions and pipe collapse. The air valves control the air in each of the following stages: Pipeline filling … read more

Hydraulically operated pressure reducing control valves reduce a higher upstream pressure to a constant lower downstream pressure, regardless of fluctuating demand or varying upstream pressure. There are different methods for applying pressure reduction: mechanical, electronic and hydraulic. BERMAD offers fully automatic hydraulic pressure reduction. In municipal networks pressure reducing valves are required at the inlet … read more

Flow control valves are designed to establish a constant pre-set maximum flow rate, regardless of fluctuating demand or varying system pressure, in order to prevent the supply system from over consumption (see below graphs). There are different methods for applying flow control: mechanical, electronic and hydraulic. BERMAD offers fully automatic hydraulic flow control.
