EMI's interlocking check ring valve is a great design choice for general-purpose material applications. Its self-cleaning flow paths provide for quick material changes, and the ring rotates with the valve body to aid in reduction of any possible flute wear during processing.

Interlocking Valve

The most reliable and highest quality 4-piece valve available. Five generous flow paths for the melt minimize the risk of shear burning. If the check ring's front seat begins to wear, that's all you have to replace...you're back up and running fast without replacing the whole assembly. For general-purpose resins, some engineered and fiber-filled materials. Good screw recovery rates, fast shut off and four times the seating area of a ball check, resulting in more positive seating force.

Valve Material Descriptions Item Description Ring Valve Resin

H-13 Tool Steel & Nitrided H-13 is a hot work tool steel having the ability to maintain hardness in high temperature atmospheres. It is therefore an excellent choice as a base material for nitriding which is performed at temperatures exceeding 1000 F. The body, ring and seat are hardened to R/C 45-50 then nitrided, creating an extremely hard case of .015"-.018" depth and a very smooth "slick-like" surface equivalent to R/C 68+. General purpose and filled materials. CPM 9V Tool Steel CPM grade 9V has a hot work steel analysis with a high carbon and vanadium content. This chemistry provides superior wear resistance not offered by any other specialty tool steel. CPM-9V also has exceptional torsional strength required for molding. Body, ring and seat are hardened to R/C 53-56. General purpose, engineered and filled materials. CPM S90V Stainless Tool Steel Offers the same high wear resistance and technology as CPM 9V combined with the corrosion resistance of 440C stainless steel. Body, ring and seat are hardened to R/C 53-56 and the stud is drawn to R/C 45-49. General purpose, filled and filled corrosive materials.
