100% automatic, self-actuating systems. Explore our robust range of valves and gates designed for zero-maintenance reliability.
Self-actuating control for reservoir inlets, canal offtakes and supply lines — built in corrosion-resistant materials and sized to your site conditions.
Controls reservoir inflow automatically from the line pressure it manages. Configured for top-entry or bottom-entry installations.
Control valve for precise flow and closing off for irrigation dams, with manual locking device if required.
Automatically regulates flow into irrigation supply lines and holding dams, shutting off once storage is full. A new addition to the Amanziflow range — specification details to follow.
Dams, rivers and canals demand equipment on a different scale. Every gate below is fabricated for site conditions and specified to integrate directly with our valve range.
A variable buoyancy tank continuously adjusts gate position while a float control valve maintains the desired flow rate, regulated against a measuring weir or flume.
Installed at the base of dams and river weirs to remove sediment. Automatic opening for floods and closing to retain storage.
Fully automatic, non-electro-mechanical operation — manual operation is available for scheduled flushing.
Raises the full supply level of existing or new dams by 0.5 m to 10 m. It installs on straight or curved ogee spillways without modifying the spillway crest, using a unique outward and upward motion.
Manual override for emergency drawdown or environmental releases; remote telemetry operation can be incorporated when required.
Automatic crest gate that maintains a constant upstream level, releasing only the surplus. Opens and closes automatically. Ideal for weirs and run-of-river schemes where storage is limited.
Interacts with Scour gates for sediment and debris reduced weirs.
Prevents saline intrusion on rising tides while allowing free drainage on the ebb. Operates entirely on differential head — no actuators, no power.
Fitted behind a diaphragm valve on the inland channel to regulate the discharge reaching the outfall.
A reliable fuse gate for emergency releases from extreme floods. Controls downstream release from storage, using the head of the impoundment itself to actuate.
Used together with main spillway gates for emergency. Controlled release in the event of an emergency manually quickly reinstated.
Automatically regulates downstream flow with varying upstream water levels.
Designed for dependable, continuous flow control. Large flows, excellent energy dissipation.
Our engineers will help you size, select and detail the right configuration for your head, flow and site conditions.
