For Large Openings and High Head Applications

  • Emergency (gravity) closure
  • Designed to limit gate deflection to 1/360 of its span in open channel applications, and 1/1000 of its span for gates covering submerged openings

 

Rugged and Corrosion Resistant

Steel or stainless steel construction and self-lubricating composite bearings ensure long service life.

Wheels Reduce Operating Thrust

The roller gate is designed to reduce the operating thrust with stainless steel wheels that operate on rails. The wheels are sized accordingly and spaced along the side of the gate to support equal portions of hydrostatic load.

Long-Term Tight Sealing

Resilient seals are attached across the top of the gate and on both vertical sides, with a seal along the invert for flush-bottom closure. The resilient seals are attached with stainless steel strips and retaining bolts for long-term tight sealing.

For Large Openings and High Head Applications

The Rodney Hunt roller gate is designed to control flow and reduce operating loads for large openings, high head applications, or where frequent operation is required. Permanently lubricated stainless steel wheels are mounted on each side of the gate and operate on rails, which are mounted on each side of the opening.

This illustration shows the typical arrangement of the Roller Gate wheels, rails, and seals.
