Curved Blade Valve
Curved blade valves are designed to shut off the flow of product from outlets of dry bulk storage bins, silos, conveyors, gravity flow chutes and other discharge points.
DCL’s curved blade valves are fast-acting, tight-sealing and very effective for regulating flow rates. The curved blade valve should only be used when handling fine or granular materials and particle sizes like aggregates.
DCL’s curved blade valve housing is constructed of plate steel with cross member supports. Each reinforced curved blade pivots on two flanged bearings allowing it to open and close with ease. Curved blade valves can be actuated in many ways; pneumatically for fast action, hydraulically for power, electrically for precise positioning and manually with a chain wheel or lever. The seals on the curved blade valve are designed to eliminate product leakage when the blade is in the shut off position. The seals are mounted to the housing instead of the blade, offering you easy access and replacement. Blade seals are selected according to the material being handled and are available to suit any application.
DCL offers a large selection of slide gate valves from 6 inches [152 mm] square up to 36 inches [914 mm] square. Slide gates are also available in sizes larger than 36 inches [914 mm] and in special configurations including hardened liners.
A choice of construction materials allows you to effectively handle all types of products – fine, granular, lumpy, abrasive and corrosive – and difficult dusty or sanitary applications. You can also choose from the electrical options that are best suited for your environment: NEMA 4, NEMA 4X, NEMA 7, NEMA 9, 120V/220V control, 460V/415V power, etc.
