Crest Gates for Water Level Control & Trash Sluicing
The Crest Gate stands as a spillway-style mechanism designed for precise water level control and efficient debris sluicing. Its construction features a reinforced leaf, anchored with bottom hinges affixed to the waterway floor. Movement is achieved by rotating around these hinges, allowing seamless opening and closing operations. In the lowered position, the gate leaf seamlessly conforms to the spillway crest profile. Typically, operational control is facilitated by a hydraulic cylinder, strategically mounted on an adjacent pier. For longer Crest Gates, a hydraulic cylinder at each end ensures optimal performance. Alternatively, cylinders can be positioned under the gate or within a vault, connected to the hinged torque tube, a configuration aptly referred to as a Torque Tube Crest Gate. This innovative design ensures versatile and efficient water flow management, making the Crest Gate a reliable solution for diverse hydraulic control needs.
Employing low-friction self-lubricated bearings at every connection point ensures smooth and efficient operation throughout the Crest Gate system. Enhancing its sealing capabilities, stainless steel side seal plates are strategically embedded in the walls, guaranteeing a continuous seal at all positions.
The versatility of the Crest Gate extends to its ability to be securely held in any position, allowing for precise control in maintaining upstream water levels. Gate position sensors, programmable in collaboration with operators, enable the modulation or restoration of the gate position as needed, providing a dynamic and responsive solution.
In addition to its advanced control features, the Crest Gate excels in handling challenging environmental conditions. Specifically, it proves to be an exceptional choice for efficiently passing ice and floating debris downstream, further showcasing its robust design and adaptability in diverse operational scenarios.
