Knife Gate Valve

Description

Aerodyne Environmental announces the StopTight®Knife Gate Valve. This dry material handling valve is the easiest and most economical way to control flow in a bulk-material handling system. The Knife Gate can manage the flow of gravity-fed solids, powders, and granules from hoppers, silos, screw conveyors, mixers, and gravity chutes. The Knife Gate is ideal as a manual shut-off for rotary valves during maintenance on the rotary valve. The Knife Gate is also available with a pneumatic drive.  The StopTight Knife Gate has a thin design that allows it to operate where most other valves cannot be placed. Its tapped inlet and outlet flanges provide easy installation for in-line or open discharge use.

The slide plate is supported by adjustable cam-guides. A seal around the slide plate prevents excess material from being pulled out while the valve operates. The Knife gate is available in standard (200°F) and high temperature (300°F). Using a linear motion, a blade advances until the passage is closed or withdraws until the passage is open. When the passage is closed, the valve is seated tightly and prevents any significant loss of positive or negative pressure from the material handling system. This low-cost material handling valve is available in 4", 6", 8", 10", and 12" sizes. The cast aluminum body and 304 stainless steel slide plate equips this valve for a wide range of materials such as chemical, foodstuffs, and plastics.
