Fine and lightweight abrasives require more controlled metering than mainstream abrasives. The Schmidt keyslot sleeve replaces the standard sleeve in the Thompson II abrasive metering valve for metering this type of abrasive. The keyslot sleeve design assists metering difficult abrasives in two ways.
- By allowing lower flow rates than other designs.
- By allowing better control over the rate of increase/decrease of abrasive flow.
Manufactured from tungsten carbide for better abrasion resistance.
