Alpheus “AS” Range
Low cost system for accurate flow control, in areas where the risk of blockage is low. The system is design for installation in a wet chamber, the designed discharge rate is accurately controlled, irrespective of head, up to 5m. Flow control is achieved with the help of a float, located inside the Alpheus’ bell housing. 
Applications
The Alpheus AS is suitable for:
- Inlet Works
- Retention Tanks
- Balancing Tanks
- Rain water systems
Benefits
- No headloss
- No external power requirements
- Consistent outlet flow irrespective of water level upto 5m
- Factory calibrated to exact pass forward requirements
- Can be recalibrated
- Minimum maintenance
- Stainless steel construction as standard
- Compact design allowing ease of installation in confined spaces
- Can be utilised in rectangular and circular chambers
- Suitable for retrofitting into existing chambers
- Built in manual override to clear blockages
- Key moving parts above the water level
Flows
AS range can pass forward flows between 2 and 2400l/s
Sizes from DN100 & DN1000
Alpheus “AA” Range
Due to the presence of sewage related debris it is possible for the standard version of the Alpheus flow limiters to suffer from blockages. These can be overcome by operating personnel using a manual pull device. To minimise the need for operator intervention, the Alpheus AA is the ideal solution. The flow regulation of the Alpheus AA is identical to that of the Alpheus AS, however in addition to the manual pull device, the AA has a system, which automatically detects and clears most blockages. The AA should be given preference, over the AS, in combined water systems and for low pass forward flow rates (<10 l/s). The AA is suitable for installation in wet chambers only. 
Applications
The Alpheus AA can be installed in:
Sewers
Retention Tanks
Inlet Works
Balancing Tanks
Benefits
No head loss
No external power requirements
Suitable for wet installations
Automatic De - Blocking
Consistent outlet flow irrespective of water level
Factory calibrated to exact pass forward requirements
Easy onsite recalibration
Minimum maintenance
Stainless steel construction as standard
Compact design allowing ease of installation in confined spaces
Can be utilised in rectangular and circular chambers
Suitable for retrofitting into existing chambers
Built in manual override
Key moving parts above the water level
Flows
AA range can pass forward flows between 2 and 185l/s
Sizes from DN100 & DN350
Alpheus “ATK” Range
The Alpheus “ATK” Flow Regulator combines all the attributes of the AT unit, but is designed to be installed in wet chambers. Its robust design and auto de-block function makes this unit the ideal solution for hassle free flow control. Its self-contained assembly means it is perfectly designed for installations in wet chambers, eliminating the problem of ragging of integral components. 
Applications
The Alpheus ATK can be installed in:
Storm Water Storage Tanks
Sewers
Retention Tanks
Overflow Chamber
Benefits
No headloss
No external power requirements
Suitable for wet installations
Automatic De-blocking
Consistent outlet flow irrespective of water level upto 4m
Factory calibrated to exact pass forward requirements
Easy onsite recalibration
Minimum maintenance
Stainless steel construction as standard
Compact design allowing ease of installation in confined spaces
Remote control option available
Can be utilised in rectangular and circular chambers
Wall or flange mounted
For use in storm or combined flows
Flows
AT range can pass forward flows between 2 and 680l/s
Sizes from DN100 & DN600
SA valves
The SA valve is used when it is desirable to completely close a chamber inlet/outlet at a predetermined water level within the chamber. The SA can be used to limit the top water level as well as a non-return valve. The SA is a reliable non-powered alternative to an electrically actuated penstock. 
Applications
SA Valves can be used to:
Regulate and divert rain water within a channel separation system
Control the inlet rate into a pumping station wet well
Control the top water level in a chamber
Prevent floods, especially during power cuts
Benefits
Installed on the wet side, so no separate chamber is required
Space saving and no complicated benching required
No need for a head loss
No power required
Manufactured from stainless steel (304 & 316), corrosion resistant
High efficiency at a low capital and running cost
Compact, suitable for retro fitting into existing chambers
Quick and easy installation
Flows
As standard, units are available between DN100 and DN1000
Custom built designs are available on request
SWDS Valves
The SWDS valve is a float-operated valve. It is used to limit the outlet flow from a tank or sewer. During storm activity the chamber will fill and exceed the hydraulic capacity of the valve, leading to backing up in the chamber. The float will rise with the water level progressively closing the gate plate as it does so. 
Applications
SWDS Valves can be used to limit flows of combined and wastewater from:
Storm water retention tanks
Storm water tanks
Sewers
Benefits
Manufactured from stainless steel (304 & 316), corrosion resistant
Wall or flang
Flow regulators -Vortex Flow Regulators.
The Stormwater360 vortex flow regulators is an efficient and convenient tool for regulating flow rates through storm sewer or combined sewer systems. When you need to control flow, whether you are working on an underground detention system, detention pond outlet control, energy dissipation structure, or combined sewer overflow (CSO) abatement plan, Stormwater360 vortex flow regulators can provide an effective and cost-efficient solution. |
