Weir Penstock – AQUIKO Level & Flow Control Gate

The AQUIKO Weir Penstock is engineered for precise water-level regulation, flow control or diversion of floating debris in drainage, surface water and sewage applications. Manufactured in stainless steel 316L for robustness and ease of installation, this gate allows the crest height of the weir to be adjusted by raising or lowering the door plate, providing fine control of upstream water levels.

Key Features & Benefits

• Vertically-sliding gate plate to adjust the effective weir crest — ideal for level control rather than just binary open/close operation.

• Lightweight stainless steel 316L construction enables easier handling and installation, without compromising strength.

• Wall-mounted installation — no requirement for grouting, enabling faster installation and reduced civil work.

• Integrated EPDM seal, self-aligning gate design — minimal maintenance, fewer greasing points.

• Suitable for systems requiring both water-level regulation and debris management (floating scum, surface flows).

• Ideal for both contractor stock lines and reseller portfolios — specification flexibility, strong build, reliable supply.

Technical Specification Snapshot

• Material: Stainless Steel 316L (standard) – for corrosion resistance and long service life.

• Gate Operation: Single central spindle or twin spindles available to prevent crabbing or reduce snagging of debris.

• Mounting Style: Wall-mounted penstock with vertical slide gate plate; no grouting required.

• Weir Crest Adjustment: Gate plate can be raised or lowered to vary upstream water level — essentially acting as a weir gate rather than a simple isolation gate.

• Maintenance: Low-maintenance design — self-aligning, integrated seals, minimal greasing required.

Typical Applications

The AQUIKO Weir Penstock is especially suited for:

• Surface water systems where upstream level must be controlled precisely (for example in storm water retention, attenuation basins).

• Sewage treatment and process water applications where floating debris or scum must be diverted or kept away from critical equipment.

• Water management installations needing fine adjustment of water height rather than just open/close isolation.

• Reseller stock lines for contractors working on civil drainage or water infrastructure requiring reliable specification and delivery.

Why Choose AQUIKO Weir Penstocks

When you choose AQUIKO you benefit from:

• UK manufacturing and supply – offering shorter lead-times, local logistics and strong support for UK contractors and resellers.

• High-spec build quality – stainless steel 316L, integrated seals, proven design for level regulation and flow control.

• Specification flexibility – options such as twin spindles, alternative actuation (rising stem, rack-and-pinion, hydraulic), accessories to fit your project needs.

• Support-ready – detailed data sheets, drawings, accessory kits, installation advice all available to support your specification and delivery.

Ordering & Availability

Standard units are available for rapid dispatch; bespoke sizes and configurations (e.g., larger spans, special actuation or materials) are available on request. Provide your project details including:

• Aperture width and height

• Required operational head or water level regulation range

• Material/environmental requirements (if more aggressive than standard)

• Desired actuation option (manual hand-wheel, electric actuator, hydraulic)

• Mounting details (wall face, channel, existing chamber)
  Our team can then provide a quote and lead-time to suit your schedule.
