Overshot water control gates are a popular product, beneficial across a variety of applications.
AWMA’s LayFlat is an overshot gate design with over 20 years proven operation, a certified flow algorithm, is custom designed to meet all specifications and manufactured to the highest international standards.
LayFlat Gates are available in marine grade aluminium, suitable for fresh water applications, and stainless steel for extended design life and/or aggressive service applications.
AWMA were engaged to design, manufacture and supply two (2) LayFlat Gates to replace existing, ageing infrastructure which had reached the end of their service life.
The new gates were specifically designed to fit into the existing structure, deliver superior seal performance and reduce the need for regular ongoing maintenance.
The retrofit design was to meet the exact size and aperture specifications, utilise the existing anchor points and have built-in electrics for instant plug-and-play capacity. A unique rubber hinge was engineered for a 30-35 degree stationary angle to reduce any factors of fatigue and further increase longevity of the LayFlat hinge. Should it be required, replacing the hinge was also made easier with an integral retainer with tapped bolts.
The headstock design was modified to position the actuator and optional hand wheel on the side instead of in the middle, for ease of operator access.
Client supervision of the gate's, Factory Acceptance Testing procedure allowed stakeholders and operators first-hand experience with the manufacturing process, installation requirements and operational capacity of the gates prior to on-site commissioning.
As the LayFlats supplied were classified critical infrastructure, a seamless replacement process was vital for plant operation.
