Weir gates are used to control the water level on one side of a gate and are characterized by opening downward to allow the flow of water over the top of the slide.
For Flow Control Where Water Flows Over The Slide
The Rodney Hunt downward opening weir gate is used for flow control in various applications where water flows over the slide. Our weir gate features a stainless steel flange back and a reinforced slide.
Exclusive UHMWPE Seals
The side and top seals of the Rodney Hunt weir gates are made from self-lubricating ultra high molecular weight polyethylene (UHMWPE), allowing no metal-to-metal contact. With a friction coefficient of 0.2, the seals make the gate easier to operate, even after long periods of non-operation. The “self-adjusting” feature is achieved by a continuous compression cord that ensures a tight seal between the slide and the frame in both seating and unseating conditions. The wedging action of the compression cord enables the gate to control flow by only allowing water through the open portion of the gate.
