This is the only true 100% free-flow ring-valve in the industry! Generous, self-cleaning flow paths minimize residence time, provide excellent screw recovery rates and allow color changes to be made easily. Highly polished radiused surfaces and an exceptionally non-compressive design make it an excellent choice when running shear, compression-sensitive, or fiber- filled materials. Excellent shut-off capabilities and a compression ratio of approximately 2:1, provide outstanding performance for more than 90% of all material applications. The Control Flow is an excellent choice for shear sensitive materials. Smooth, wide flow patterns and low compression allows shear-sensitive materials to be run with ease.

100% Free Flow Control Flow The extended life of this valve provides many profit- boosting benefits

The 3-piece, 4-fluted carbide insert ring valve is made of H-13 and features carbide inserts at the base of each flute. The carbide inserts protrude slightly from the flute allowing the inserts to ride against the ring rather than the flute itself. This has proven to be extremely effective in preventing wear in this area (95% of all valve wear is usually in the flute area).

Carbide Inserts

EMI has also incorporated the inherent wear resistance of carbide inserts with the premium flow characteristics and processing capabilities of the EMI Free Flow.

*Due to possible design limitations and the need to assure adequate material exists for imbedding carbide inserts, please consult EMI to determine if a Free Flow Carbide Insert Valve can be produced for your application. Note: While the carbide inserts protect only the flute area, adhesion wear (gauling) is usually very minor, resulting in less than 5% of valve replacement.
