The valve body openness provides space for the product to be freely displaced by the lever arm and disc with each cycle. Fines cannot compact in small open areas and possibly jam components, as is the case with other valve concepts. Each time the valve opens to discharge product, a vortex is caused by the eccentric body to port configuration. The settled media swirls, thereby cleaning the valve's interior.
The disc or discs are not fixed to the lever arm (applied force), but are free to rotate about the spring-loaded rivet with every valve cycle. The disc and seat ID have sharp edges that serve to shear away deposited media from the sealing surfaces as the valve strokes. No other valve is similar.
