Overshot Weir Penstocks- Precise level control
- Quick and Easy to install
- Lightweight yet robust
- Virtually maintenance free
- Accurate level control
- Low torque to operate
ACE Overshot Weir Penstocks are an ideal way to accurately control water levels, adjust flow rates, or even divert floating debris/scum away from operational equipment. The penstocks are manufactured in Stainless Steel 316L, making them lightweight for ease of handling and installation, without compromising strength.
The ACE Overshot Weir Penstock comprises a sluice gate that moves vertically, adjusting the height of its crest to allow the water level upstream to be maintained. Common uses include:
- Fine accuracy water level control and flow diversion in-process applications
- Penning of differing winter and summer levels
- Decanting of scum and floating debris
Overshot Weir Penstocks are wall-mounted, with no requirement for grouting, making them quick and simple to install, with all the mounting accessories supplied in the ACE package- the majority of Overshot Weir penstocks can be bolted and sealed to the wall in less than a single shift, with no fiddly setup.
Once installed, ACE penstocks require very little attention, as greasing is not required in most cases, and the construction of the penstock gate is self-aligning, with no fiddly wedges, and an integrated EPDM seal.
The Overshot Weir Penstock is available as standard with either a single, central spindle or twin spindles to prevent crabbing or to reduce snagging of floating debris. Although the spindle is centrally positioned, it has a unique drive arrangement to prevent collision with debris. In both cases, this can be replaced with rising spindles, rack and pinion drives, or hydraulics, and in all cases, the equipment can be manually driven, or electrically operated, along with automation if desired.
Although ACE have a range of standard designs of Overshot Weir Penstocks, our penstocks can be customised to suit specific requirements, either to adhere to particular specifications, or to save complicated construction, or modification to existing structures.
