Dry material handling valve
The Aerodyne Environmental StopTight knife gate valve controls the flow of gravity-fed solids, powders and granules from hoppers, silos, screw conveyors, mixers, and gravity chutes. It is used as a manual shutoff for rotary valves and is available with a pneumatic drive. The valve can operate in small places and be installed for inline or open discharge use. The slide plate is supported by adjustable cam guides. A seal around the slide plate prevents material from being pulled out while the valve operates.
