500 Series – Bulkhead Gates

Heavy-Duty Bulkhead Gates for Tough Applications
Made in the USA since 1977

General Information

Whipps, Inc.’s 500 Series Bulkhead Gates are engineered for the most demanding flow control applications, offering heavy-duty performance in high head conditions and large waterways. Built with reinforced construction and precision fabrication, these gates are designed to provide long-term reliability, durability, and ease of use in municipal, industrial, and treatment facility environments.

The Model 519 Bulkhead Gate functions as a heavy-duty aluminum stop gate, making it an ideal choice when corrosion resistance and lightweight handling are key considerations. Its large slide is manufactured from extruded aluminum (Alloy 6061-T6) and designed to withstand a maximum bending stress of 7,600 psi at the maximum head. To ensure a tight, low-leakage seal, resilient lip-type seals are attached along the sides and bottom of the slide. The frame, which includes two grooves and an invert member, is also constructed from Alloy 6061-T6 aluminum and comes supplied with stainless steel anchor bolts or aluminum anchor straps. The invert member is engineered specifically to minimize flow interference, enhancing overall hydraulic efficiency.

The Model 519-C Bulkhead Gate shares the same rugged, reinforced aluminum construction as the 519 model but is designed as a channel-mounted option. This configuration provides added versatility for installations where channel mounting offers improved accessibility or operational performance.

For applications requiring maximum strength and corrosion resistance, Whipps offers the Model Stainless Steel 529 Bulkhead Gate, constructed from stainless steel (Type 304 or 316). Like the aluminum models, the 529 model features a large, extruded stainless steel slide equipped with resilient lip-type seals along the sides and bottom to maintain reliable sealing performance. The stainless steel frame is built with two grooves and an invert member, supplied with stainless steel anchor bolts or straps, and designed to minimize flow interference. This makes the 529 bulkhead gate an excellent choice for the most aggressive operating conditions, including harsh water environments and facilities requiring long-term, low-maintenance solutions.

With options in both aluminum and stainless steel, and configurations for embedded or channel-mounted installations, Whipps 500 Series Bulkhead Gates provide a durable, adaptable, and dependable solution for controlling high head flows in critical water management systems.

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.

500 Series Bulkhead Gate Videos

In this video, we take a closer look at the Whipps 500 Series Stop Gates — a simple, effective, and reliable solution for isolating water flow in municipal, industrial, and environmental systems. Watch as operators easily lift and place these lightweight, rigid panels into position. Designed for manual installation and removal, each gate fits seamlessly into its channel frame, making it the ideal choice for sites that require temporary flow stoppage without complex tools or equipment. Crafted from high-quality aluminum or stainless steel, our stop gates provide a strong yet manageable design. Precision-fabricated handles and durable UHMW seat seals deliver tight, low-leakage performance even in challenging conditions. You’ll see both material options in action: 501–503 Series — Lightweight aluminum for low-pressure or remote locations 521–523 Series — Rugged stainless steel for high-pressure or corrosive environments After the job is complete, the gate is simply lifted out and stored for future use — making the 500 Series a clean, efficient, and dependable part of any water management operation.
