823-I – Dual Stem 820 Slide Gate
A wider version of Whipps, Inc.'s aluminum Model 823 slide gate, incorporating a second stem for support. An addition that ensures stability and functionality beyond the standard 823 design dimensions.
General Information
The 800 Series Aluminum Gates from Whipps, Inc. are expertly engineered to deliver exceptional performance and durability in a variety of flow control applications. Designed with robustness and longevity in mind, these gates offer efficient water management solutions that meet the demands of diverse operational environments. Whether you require standard gates or customized solutions, Whipps, Inc. provides rapid and cost-effective production to meet your specific needs.
Constructed from rugged, reinforced aluminum, the 800 Series Gates are built to withstand the rigors of continuous use while maintaining their structural integrity. The use of ultra-high molecular weight polyethylene (UHMW) seat/seals enhances the durability of these gates, providing a reliable and flexible sealing solution. Our highly skilled craftsmen and engineers ensure that the gates remain operational under varying flow conditions and mounting configurations, delivering consistent and reliable performance.
Customized gate frames are available to accommodate any combination of wall mounting, channel mounting, or embedding. The reinforced slide is lowered into the frame during installation and can be raised or lowered to open, depending on the site’s constraints. The width of the slide gate determines whether an additional stem will be added to the assembly, ensuring consistent and smooth gate travel during operation.
One of the standout features of the 800 Series Gates is their resilient bottom seal, which guarantees a secure and flush bottom closure. This design minimizes leakage and enhances the overall effectiveness of the flow control system. The aluminum material used in the construction of these gates ranges from 1/4” to 3/8” thick, providing the necessary strength and rigidity to handle demanding applications. Thanks to our ability to manufacture our products ourselves, we are proud to offer rapid and cost-effective production.
Whipps, Inc. is committed to delivering high-quality products that meet both standard and specialized requirements. Our aluminum gates are produced with a focus on rapid turnaround and cost-efficiency, ensuring that you receive the best value for your investment. We encourage our customers to reach out to tell us exactly any unique characteristics required. Additionally, we offer customization options to address unique applications, allowing you to tailor the gates to fit specific operational needs.
In summary, the 800 Series Aluminum Gates from Whipps, Inc. represent a superior choice for efficient flow control. Their rugged construction, durable sealing materials, and flexible design make them ideal for a wide range of mounting configurations and flow conditions. Trust Whipps, Inc. to provide reliable and high-performance aluminum gates that meet your precise requirements with excellence and efficiency.
Product Advantages
Superior Performance
Whipps, Inc. provides a leakage guarantee that surpasses the specifications outlined in AWWA C-501 for Cast Iron Sluice Gates or the most recent revision of AWWA C-560 for Cast Iron Slide Gates. Our commitment ensures leakage rates not exceeding 0.10 gpm/ft of seal perimeter under both seating head and unseating head conditions, even in high head service scenarios.
Cost
Fabricated aluminum gates usually provide a cost advantage over cast iron gates. The manufacturing process for aluminum gates is generally less expensive than that of cast iron, stainless steel, and fiberglass gates.
Durability
Aluminum has proved to be a suitable material to use in most water and wastewater. Our aluminum gates feature UV-stabilized UHMW seat/seals, which are field proven to maintain shape and integrity in demanding applications. Whipps, Inc. conducted rigorous testing on UHMW seat/seals. Subjecting them to 25,000 gate open/close cycles in an abrasive media to validate their ability to withstand continuous operation with minimal wear. (Test results available upon request.)
Reliability
The slide of the aluminum gate will not ‘freeze’ to the frame after extended periods of inactivity. This is achieved through the inclusion of UHMW seat/seals, which effectively eliminate metal-to-metal contact between the slide and the frame.
Delivery
The process of fabricating an aluminum gate from raw materials is notably quick, particularly because Whipps, Inc. keeps most materials in stock.
Self-Adjusting Seals
The aluminum gates that Whipps, Inc. offer are equipped with a self-adjusting seal system that eliminates the need for field adjustments. A solution particularly advantageous for gates installed in locations where such adjustments are impractical or unfeasible. This advanced system cannot be replicated by the imprecise method of adjusting wedges, which can lead to increased leakage, localized stress, and difficulty during gate operation. Our self-adjusting seal system consists of UHMW, much more durable than rubber J or P seals. While rubber seals can crack, flatten, and/or adhere to the slide, our UV stabilized UHMW seat/seals will not. Furthermore, the seal system boasts a lower coefficient of friction compared to rubber, reducing the effort required to operate the gate.
Low Maintenance
Aluminum gates do not need periodic painting and require less operator attention when compared to cast iron or stainless steel gates.
Ease of Repair
In the rare event of the seat/seals experiencing damage, they can be readily replaced in the field using common tools, without the need to dismount the gate from the wall. In contrast, the damaged seating surface of a cast iron gate necessitates the removal of the gate from the wall and must be shipped back to the manufacturer for remanufacturing.
Range of Sizes
The process of designing and manufacturing fabricated gates offers the flexibility of producing a wide range of sizes, nearly without limits. In contrast, cast iron gates require the creation of new patterns or modifications to existing patterns to accommodate uncommon sizes.
Mounting Configurations
Gate frames can be either embedded in channel walls or mounted to a wall, pipe flange, or wall thimble. Wall thimbles are recommended for applications with high unseating head conditions. We offer flanged frames or flat frames for gates designed to cover square, rectangular, or round openings in concrete structures.
