Front Discharge Ring Valve

This check valve offers the best all-around precision shot control available.

Excellent choice for running non-shear-sensitive, general purpose materials. Low cost, removable ball check inserts can be interchanged for various compressions and recovery rates. Year after year, molders have preferred EMI’s ball check valve because of its dependability and consistency.

Standard: 4150 pre-treated steel. Optional: 440C stainless steel or CPM 9V tool steel. Inserts available in S-7 tool steel.

Hi Flow

Ideal for high speed molding of general purpose materials which normally require a ring valve.

Front Discharge Ball Check Valve

EMI Hi-Flow ball check valves feature extra large inlets and flow paths to dramatically increase melt flow while cutting compression ratios down to 1.5:1. Recovery times are cut without sacrificing precision shot control. Included: Includes EMI’s exclusive, low cost, removable ball check insert which is interchangeable for various compressions and recovery rates.

Standard: 4150 pre-treated steel. Optional: 440C stainless steel or CPM 9V tool steel. Inserts available in S-7 tool steel.

Side Discharge

The most reliable and highest quality four-piece valve available.

This ball check valve gives you excellent shot control, enhanced mixing action, is self-cleaning and purges rapidly via a “washing” action between the nose cone and end cap, making it ideal for fast color changes. Replaceable, low-cost ball and ball seat minimize maintenance costs and downtime. Hand seated interfaces ensure a tight seal. This is an ideal valve for general purpose, non-shear-sensitive materials where frequent color changes must be made.

Standard: 4150 Pre-treated steel. Optional: 440C stainless steel or CPM 9V tool steel.

Replacement Inserts

Available in three styles to suit specific application needs.
