Show all Water Control Gates Manufacturers

Water control gates are used to control the mass flow of water or wastewater in various environmental and process applications. They are usually square and rectangular in shape and made of stainless steel or galvanized aluminum.

Types

There are many different types of products. Bulkhead gates are supplied in one-piece panels and used in flood control applications. These large water control gates are installed with a hoist or crane and may include stop logs for ease of installation. Floating bulkheads consist of individual sections that are floated in place and joined together. These water control gates are designed for spillway openings and other areas that cannot use a bulkhead gate. Slide gates have neoprene or elastomeric seals and are actuated with hydraulic cylinders or manual gear drives. Roller gates are designed for openings that are too large for slide gates, or that require gravity closure. Crest gates feature bottom hinges and rubber seals. They are hydraulically-actuated and designed for water level control. Tainter gates are operated by hoists and consist of a curved plate and radial arms. Miter gates are used to control access to navigational locks and canal systems. Bonneted slide gates are lifted vertically and operated electrically or hydraulically. Ring follower gates are slide gates with a solid section that blocks the waterway and a circular opening that provides a water passage. Jet flow gates, another type of slide gate, are designed for free discharge and flow regulation. Water control gates include fish diversion gates, jet flow gates, multiple leaf gates, sector gates, sluice gates, timber gates, tipping plate regulators, and velocity control gates. Fish diversion gates are used by wildlife management agencies to facilitate the movement and tracking of fish and other aquatic life. Jet flow gates are water control gates that combine high-head energy dissipation with excellent flow regulation for minimum cavitation and vibration. Multiple leaf gates are suitable for applications with limited headroom. Sector gates are vertical tainter gates used for flow control in locks and dams. Sluice gates feature sealed, self-contained, or integral frame designs. They are usually made of cast iron and used at the end of pipelines. Timber gates are made of iron and wood and differ in terms of seating pressures. Tipping plate regulators combine sewage flows in sewer interceptor lines. Velocity control gates are used to divide flow between channels and may include trash screens. Other types of water control gates are also commonly available.
