Operation and maintenance of equipment located downstream of a cooling water intake is critical for the applications uninterrupted operation. The StopGate™ solution, designed by Eimco Water Technologies, provides a seal isolating flow streams for safe, dry and easy routine maintenance on downstream screening equipment and pump intakes.

The Brackett Green StopGates™ is custom built to withstand the design differential for the particular application.

The gate is welded construction, fabricated from steel plate and rolled steel sections and fitted with neoprene edge seals. General gate construction is carbon steel with a coal tar epoxy paint finish providing the necessary corrosion protection. The Stop Gates are fitted with equalising valves to balance the water levels either side of the gate.

A single piece StopGate™ is normally designed for installation at the bottom of the channel with a civil work apron wall extending up from the top of the opening, to deck level. However the stop gate can be supplied in sections with one section arranged to locate above the other so that it extends above the highest water level, removing the necessity for a concerted apron wall.
