Vortex Roller Gates for a dust-tight material seal.

The Vortex Roller Gate is a superior choice for handling dry material in gravity flow or low-pressure applications where dust tight sealing is required. The Roller Gate is available in a wide variety of configurations including rectangular sizes and specific customer bolt patterns. Roller Gates are ideal for many dry material applications such as mixing and blending. The Roller Gate can be applied to shut off, or meter, the flow of fine and moderately abrasive powders, and small to large granulars or pellets. It also handles sticky materials, can be installed horizontally or vertically, and is ideal for the food, cement, chemical, plastics, and textile industries.

The Vortex Roller Gate has live-loaded wear compensating seals that prevent materials from escaping into the bonnet area of the gate. These seals are easily replaced without removing the valve from the processing line. The Roller Gate utilises easily accessible, nylon cam-adjustable rollers instead of blade guides – a feature that is critical to avoid material packing. The Roller Gate can also be fitted with an optional return pan to prevent material leakage into the atmosphere.

Adapting the Roller Gate to a system is made easy with a wide selection of gate positioning controls, position indication switches, and flanges. The Roller Gate also offers a wide variety of modifications to accommodate a range of temperatures, corrosive, humid, and explosive environments. Vortex Roller Gates also offer a wide variety of actuation choices including electric hydraulic, pneumatic, chainwheel, and hand crank. Standard sizes are 100mm to 760mm (6” to 30”) with an aluminum channel frame and stainless steel material contact. Options include rectangular sizes, stainless steel construction, inlet/outlet transitions, seal access ports, removable seals, and more.
