Flagship equipment
The award-winning equipment Amanziflow is known for
The automatic, self-actuating systems at the heart of most of our installations — storing more water, keeping it clean, and handing it on precisely where it is needed.
AG-TOPS · Spillway gate
TOPS Spillway Gate
Raises the full supply level of existing or new dams by 0.5 m to 10 m — increasing storage without raising the dam wall.
It installs on straight or curved ogee spillways without modifying the spillway crest, using a unique outward and upward motion that rides on the water it stores — no external power, sensors or controllers required.

raised full supply level per dam
AV-DM · Flow control valve
Diaphragm Valve
Control valve for precise flow, and closing off for irrigation dams when storage is full.
A line-pressure diaphragm operator regulates flow and head without motors or power. A manual locking device is available where the valve must be held shut for maintenance or isolation.
Precise flow and head control
The diaphragm operator holds the set flow across the working head range.
Shuts off when storage is full
Closes the supply to irrigation dams rather than overfilling them.
Manual locking when required
A locking option holds the valve in position for maintenance or isolation.

AG-SC · Sediment removal
Scour Gate
Protects dam storage by flushing sediment before it settles — and restores full supply level as floodwaters recede.
Installed at the base of dams and river weirs, it opens automatically during flood events to pass sediment-laden water, then closes automatically to retain the full supply level. No electro-mechanical operation and no external power.
Passes sediment in flood
Opens automatically during flood events to flush sediment-laden water downstream.
Retains supplied storage
Closes as floodwaters recede — holding back water instead of releasing it.
Self-actuating, no power
Runs on non-electro-mechanical actuation, with manual operation for scheduled flushing.

The Amanziflow DifferenceLearn about our legacy
Self-actuating by design. Dependable by nature.
Our valves and gates harness the very water they control. There are no motors, no PLCs and no batteries to fail — just proven hydraulic principles engineered to operate through storms, outages and decades of service.
No external power
Fully self-actuating: the equipment runs on the pressure and level of the water itself.
No operator error
Removes the human variable from flood response and level control, day or night.
Built to outlast
Marine-grade fabrication and pressure-tested assemblies for Infrastructure that must endure.
