953-C – Heavy-Duty Channel Mounted 950 Slide Gate

The Model 953-C Channel Mounted Slide Gate is a variation of the standard 953, designed with a channel-mounting configuration for applications where embedment is not possible. Built from the same high-quality stainless steel as the rest of the 900 Series, it offers dependable sealing, long-lasting corrosion resistance, and reliable performance.

General Information

The Model 923-C Slide Gate from Whipps, Inc. is a versatile, corrosion-resistant solution designed for precise water control in a wide range of applications. Part of our stainless steel 900 Series, the 923-C is categorized as a sluice gate but is built without a top seal, allowing water to overflow if levels rise above the top of the slide; ideal for installations where controlled overflow is required.

Unlike wall-mounted designs, the 923-C utilizes a channel-mounting configuration, making it the perfect choice for applications where embedment into the structure is not possible. This setup provides secure installation, reliable alignment, and dependable sealing performance while maintaining ease of access for inspection and maintenance.

Each gate is custom-fabricated to meet project-specific requirements, with precision components engineered for smooth and consistent operation. Sizing follows the same Width × Head formula used across the 900 Series: totals of 80 or less call for the Model 920 standard-duty gate; totals over 80 and up to 120 require the Model 930 medium-duty design; and higher loads or larger openings exceeding 120 may require the heavy-duty Model 950 configuration. This ensures every gate is engineered to match its operating pressures and flow conditions.

From wastewater treatment plants to irrigation channels and flood control systems, the Model 923-C delivers dependable, low-maintenance performance. Constructed from high-quality stainless steel with UHMW seals for long-lasting leak protection, these gates are backed by Whipps, Inc.’s commitment to quality and designed to perform reliably for decades with proper care.

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.
