500 Series – Stop Gates
Best Stop Gate For Minimal Leakage
Made in the USA since 1977
General Information
The 500 Series Stop Gates from Whipps, Inc. are expertly engineered to deliver reliable and effective water containment in a variety of management scenarios. Known for their robust construction and innovative design, these stop gates are a preferred choice for both standard and specialized applications. Emphasizing durability and performance, the 500 Series Stop Gates ensures optimal functionality and long-lasting reliability.
Stop gates feature a metal slide built to withstand the head pressure at the installation site. The slide is equipped with two welded handles, allowing workers to easily grasp and maneuver it. Due to the lightweight design, the slide can be lifted by one or two workers and easily stowed away until it’s needed again. This makes it ideal for applications where the insertion and removal of the slide gate are infrequent.
The core of the 500 Series Stop Gates is its rugged aluminum construction, which delivers a blend of strength and lightweight performance. This material choice provides exceptional durability while remaining easy to handle and install. Complemented by durable and flexible ultra-high molecular weight polyethylene (UHMW) seat/seals, our stop gates offer superior sealing capabilities. The UHMW seals are designed to ensure a tight, secure closure with minimal leakage, enhancing the effectiveness of the water containment system.
For applications that require enhanced durability and robustness, we also offer stop gates constructed from stainless steel. This material provides a more substantial and resilient option, ideal for environments where extra strength is necessary. The stainless steel stop gates are built to withstand harsh conditions while maintaining the high performance expected from Whipps, Inc. products. The stainless steel design ensures that the gates continue to deliver reliable containment and control even under demanding operational conditions.
Whipps, Inc. is dedicated to delivering customized solutions tailored to meet your specific requirements. Whether you need a standard aluminum stop gates or more durable stainless steel options, our expertise and resources ensure you get exactly what you need. Our stop gates are engineered to accommodate a wide range of applications, from water containment in ponds and tanks to channel management.
In summary, the 500 Series Stop Gates by Whipps, Inc. are designed to offer effective and reliable water containment with a focus on durability and performance. With options in both aluminum and stainless steel, our stop gates’ lightweight design allows for manual operation, ensuring that you receive a product that meets your exact requirements. Trust Whipps, Inc. for superior water control solutions that set the industry standard for quality and performance.
Product Advantages
Quality Assurance
The stop gate will be manufactured by a company with 10 years or more of successful experience in designing and producing low-leakage stop gates under similar design conditions. All welds will be executed by welders with AWS certification.
Performance
The maximum allowable leakage for the stop gates shall be 0.10 gallons per minute per linear foot of the wetted perimeter, regardless of the direction of the unbalanced head.
Technical Information
In addition to the submittal information required by other sections of these specifications, the stop gate manufacturer may need to submit design calculations and supporting data for all gates, illustrating stresses, loads, and deflection for critical parts under design head conditions. At a minimum, theses shall include operating load, slide deflection, slide bending stress, and shear stress in stiffener welds.
Frame
Constructed of 1/4” or thicker extruded aluminum (Alloy 6061-T6) incorporating ultra high molecular weight polymer (UMHW) seat/seal facing on both the upstream and downstream sides of the slide. Each seat/seal is shaped to provide two bearing surfaces and two sealing edges. The gate side guides and invert shall weigh a minimum of 4lbs/ft for wall mounted and 3lbs/ft for embedded installation. The gate invert shall include a removable neoprene seal. Seals attached to the slide will not be acceptable. All necessary assembly and anchor bolts shall be type 304 (type 316 optional) stainless steel and provided by the gate manufacturer.
Slide
The slide shall be minimum thickness of 1/4” aluminum plate (Alloy 6061-T6) reinforced with stiffeners as required ensure that at the design head, the slide will not deflect more than 1/360 of its width and stress is limited to 7600 psi. Slide stiffeners shall have a minimum weight of 2.5lbs/ft. The slide shall be equipped with a cast aluminum offset lifting handle. Gates wider than 36 inches shall be provided with dual lifting handles.
Painting
All aluminum in contact with concrete shall receive a heavy shop coat of bitumastic paint.
Anodizing (optional)
All aluminum components can be anodized in accordance with Aluminum Association Specification AA-C22-A41. The anodizing shall be 0.7 mm thick with a nickel acetate sealer.
