The Vortex Roller Gate is the best choice for handling dry material in gravity flow or low-pressure applications. This gate is available in a wide variety of configurations including rectangular sizes and customer specific hole patterns. It has live-loaded seals that extend the service life by compensating for wear. These seals provide an excellent material seal across the gate and to atmosphere. They can also be replaced while the valve is in-line. Similar slide gates have seals made of soft packing, rubber or felt, which rapidly erode away allowing product leakage.
