Flow Control without Energy
Adjustable PVC control gate with adjustment scale to position on vertical walls. Limits outflow in flow regulating chambers.
Adjustable gate for rectangular flow cross-sections. Optimized geometry for a small coefficient of discharge.
An active flow control device with a very high flow-resistance and a large, free-flow cross-section. Particularly suitable to control small outflows from rainwater storage basins.
Static flow controller discharging 4 to 6 times less stormwater than orifice plate. Prevents downstream flooding by allowing "flow slippage". Controls stormwater directly at source, the manhole.
The Pond vertical vortex flow regulator is both an overflow weir and a regulator for the output flow of stormwater storage tanks, swales, wetlands, etc.
Discharge throttling device to limit outflow from storage and overflow tanks or reservoirs. Discharge controlled by creating air-filled vortex that reduces effective water passage area without physically reducing orifice size The Euro type is applicable for wet-well flow control structures.
Same as HHV but discharge in two stages. Up to pre-determined upstream water level, valve operates as simple orifice. When UWL exceeds certain value, air-filled vortex forms at center of outlet reducing water passage area without physically reducing outlet size.
Flow regulator device requiring no external energy source. High passive security through the combination of a vortex valve with high flow resistance and a low-pressure hydraulic regulating plate.
Closed loop flow control with automatic stockage release. Suitable for small flows.
Membrane flow regulator used to maintain constant discharge from stormwater storage tanks and SBR's. Entirely static flow controllers enable easy disinfection treatment.
