Weir Gates

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.

Unique Self-Adjusting Seals

To assure long term tight sealing, our side and top seals are self-adjusting and are constructed of UHMWPE (Ultra-High Molecular Weight Polyethylene) with a nitrile compression cord.

Tested and Certified

All Rodney Hunt gates are tested prior to leaving the factory, undergoing 25,000 cycle testing to ensure long-term reliability.

No Maintenance Fee

Our self-adjusting J seal design eliminates the requirement for maintenance. Seals have no metal-to-metal contact to ensure no sticking, even after years of non-operation.

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.
