921–D – Weir Embedded 920 Slide Gate
This product is designed for scenarios requiring the gate to be embedded. The Model 921 from Whipps, Inc. features stainless steel construction, eliminating the need for paint coating.
General Information
The 900 Series Stainless Steel Gates from Whipps, Inc. are designed to deliver exceptional performance and durability in precise water management applications. With subseries designed for heavy-duty to standard requirements, these gates offer a versatile solution for managing water flow. With a focus on quality construction and extended lifespan, the 900 Series ensures reliable operation and performance across a wide range of applications.
The 900 Series stands out in our product lineup due to its diverse subcategories that offer rapid and cost-effective production. The 920 Series is our standard stainless steel slide gate, manufactured in-house and suitable for most applications. For high head conditions and larger opening sizes, we offer the more rugged and durable 930 and 950 Series. Each series builds on the strength and reliability of the previous one. Customized gate frames designs accommodate any combination of wall mounting, channel mounting, or embedding. The reinforced slide is lowered into the frame and can be raised or lowered to open, depending on site 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.
Crafted from stainless steel, the 900 Series Gates are built to endure the challenges of demanding environments. The stainless steel fabrication provides superior strength and corrosion resistance, ideal for applications where durability and longevity are critical. The use of ultra-high molecular weight polyethylene (UHMW) seals further enhances the gates’ performance by providing an elastic yet durable sealing solution that minimizes leakage and ensures a secure closure.
A key feature of the 900 Series Gates is the resilient bottom seal, which guarantees a secure and flush bottom closure. This design element enhances the effectiveness of the water management system by ensuring a tight seal. The gates are available in both heavy-duty to standard-duty options, allowing you to select the right level of performance and strength for your specific needs. Our team is dedicated to delivering high-quality products with efficiency and precision.
In summary, the 900 Series Stainless Steel Gates from Whipps, Inc. represent a top choice for precise water management. With their rugged stainless steel construction, durable UHMW seat/seals, and versatile design options, these gates provide a reliable solution for various flow conditions and mounting configurations. Entrust Whipps, Inc. to deliver high-performance stainless steel gates that meet your specific needs with exceptional quality and reliability. Our commitment to excellence ensures that you receive a gate that meets your exact requirements and performs reliably over time.
Product Advantages
Superior Performance
Whipps, Inc. guarantees lower leakage than that listed in AW WA C-SOI- Cast Iron Sluice Gates or the latest revision, AWWA C-560 – Cast Iron Slide Gates. Whipps, Inc. will guarantee leakage of no more than 0.05 gpm/ft of seal perimeter in seating head and unseating head conditions. Including high head service.
Cost
Fabricated stainless steel gates almost always cost less than cast iron gates. As the size of the gate increases, the price difference increases. This is due to the manufacturing process (e.g. casting of parts and subsequent machining) required to produce cast iron gates.
Strength
The ultimate strength of stainless steel is in excess of twice the ultimate strength of cast iron and stainless steel has approximately twice the modulus of elasticity of cast iron.
Durability
Stainless steel resists corrosion better than cast iron. The uv stabilized UHMW seat/seals that are utilized on our stainless steel gates are field proven to maintain shape and integrity in demanding applications. Whipps, Inc. tested the UHMW seatjseals to confirm the ability to withstand continuous operation in an abrasive environment. The testing consisted of 25,000 gate open/close cycles in an abrasive media while experiencing only negligible wear. (Test results available upon request)
Reliability
Unlike traditional cast iron gates, the slide will not “freeze” to the frame after long periods of inactivity. Whipps, Inc. stainless steel gates incorporate UHMW seat/seals to prevent any metal-to-metal contact between the slide and the frame.
Delivery
The fabrication process required to turn raw materials into a stainless steel gate is quicker than the casting and machining process required to turn raw materials into a cast iron gate
Self-Adjusting Seals
The Series 900 stainless steel gates have a self-adjusting seal system that completely eliminates the need for field adjustment. This seal system was developed with the understanding that many gates are installed in locations where field adjustment of wedges is not practical or possible. Another drawback to a wedged system is that wedge adjustment is an inexact science. Wedge adjustment when attempted by inexperienced personnel can lead to additional leakage, difficult gate operation and increased localized gate stresses. The self-adjusting seal system is a combination of durable UHMW seatjseals and a resilient static spring/seal. The UHMW seat/seals are shaped to form a low friction, yet tight, seal with the slide. The spring/seal serves two main purposes: First; it acts as a bulb seal etween the frame and the UHMW seat/seal and secondly; it acts as a “spring” to ensure continuous contact between the UHMW seat; seals and the slide. The spring/seal is stationary, similar to an O-ring seal. and it is protected from wear or damage from the movable slide by the UHMW seatjseals. (Wedges can be provided on our Series 900, but they are not recommended since they do not improve the performance of our gate.)
Low Maintenance
Stainless steel gates do not require periodic painting, and require less operator attention compared to cast iron gates.
Ease of Repair
In the unusual event that the seat/seals are damaged, they can be replaced in the field with common tools. The gate does not have to be removed from the wall. If the seating surface on a cast iron gate is damaged, the gate will have to be removed from the wall and shipped back to the manufacturer for re-manufacture.
Range of Sizes
The process to design and manufacture fabricated gates allows for a nearly unlimited range of sizes. This is not the case with cast iron gates since new patterns or modifications to existing patterns are required to accommodate unusual sizes.
Mounting Configurations
Gate frames may be embedded in the channel walls. mounted to a wall with anchor bolts, mounted to a pipe flange, or wall thimble. Wall thimble mounting is possible although it is usually only necessary for applications with high unseating heads. Gates can also be designed to mount to existing wall thimbles or existing pipe flanges. Flanged frames or flat frames are available for gates to cover square, rectangular or round openings in concrete structures.
