Beaudrey - By-Pass Valves

They are actuated by the difference in water levels between the upstream and the downstream faces and open when head-loss reaches a set level, 30 cm or 1 ft, generally speaking. The water flows through the valve.

They are used when it is essential to have a water supply even when the rotating screens are obstructed (power failure, lack of wash-water, etc.).

They are absolutely safe with no mechanical items, no power requirements nor automatic controls. If required, a signal can tell the operator if it opens.

By-pass valves may appear simple but require calculations and laboratory testing. The BEAUDREY by-pass valve is the best technology available.
