Aerodyne's StopTight manual and pneumatic knife gate valve is suited for discharging dry, free-flowing materials—especially powder—from gravity-fed hoppers, silos, mixers, screw conveyors and chutes.
This valve is also an economical and reliable way to isolate airlock valves from hoppers during routine maintenance or emergency shut-downs. A series of adjustable cam-guides support the slide plate and seal it firmly against the machined inlet seat. The cast-aluminum body and stainless-steel slide plate make this valve suitable for a wide range of materials including: chemicals, plastics and powders. The thin profile and tapped flanges allow this valve to go where most other valves can't, the company says.
Aerodyne's StopTight KG valves are available in 8, 10, and 12-inch sizes in manual or pneumatic operation.
