WLF Penstock Wedge Lock Gate

WLF Penstock's are AWMA's Wedge Lock Gate Penstock Valves. They are sluice type penstocks featuring a wedge lock seal, designed for high head applications.

Resilient seals around all four sides of the aperture.
A unique design applies a positive seal pressure as the gate fully closes providing excellent sealing under high head pressures.
Bi-directional sealing optional.
Single and dual spindle configurations available.
Both rising and non-rising spindle configurations available.
Custom designed and fabricated to suit any size or shaped orifice.

Full perimeter sealing accommodates high head pressures for excellent sealing performance across all applications.
Isolation of flow under high head applications.
Suitable in corrosive environments.

AWMA’s design team will provide full support to ensure the most appropriate solution is developed and specified during the preliminary design.

All AWMA water control gates are custom sized to ensure they meet specific site and operational requirements.
Customisation reduces installation costs.

AWMA select materials to meet a minimum design life of 25 years. Where required, AWMA can offer higher grade materials, coatings and protection systems to extend the design life to 100+ years.
AWMA use ultra high molecular weight polyethylene (UHMWPE) for penstock door guides and/or wedges to provide maintenance free bearing surfaces.
Plasticised PVC or EPDM are used for the manufacture of seals. These materials offer superior endurance in wastewater and freshwater applications.
Materials used for penstock door and frames include marine grade aluminium and grades 304, 316, 2205 and 2507 stainless steel.
Alternative material options are available to suit the application and/or environment specific requirements.
Materials used in the construction of the WLF Penstock range have a high corrosion resistance and can be operated for many years with minimal maintenance.

The sealing ability of this gate exceeds that required by the ‘Australian Technical Specification for Fabricated Water Control Infrastructure’.

The WLF Penstock range has a minimum 25year design life.
Minimal maintenance is required offering low “whole of life costs”.
If required, all the wearing components can be changed, with ease, on site.
The WLF Penstock has specifically been designed with the seals mounted on the gate leaf, rather than the frame, for ease of maintenance.

All fabrication is in accordance with the ‘Australian Technical Specification for Fabricated Water Control Infrastructure’.
All stainless steel welding is continuous to avoid crevice corrosion.
All procedures are in accordance with AWMA’s accredited ISO 9001 Quality Management System to ensure each gate is manufactured to a high standard, tested and ready for trouble free operation post approved installation.
