Pressure Seal Tilting Disk Check Valve

• Uncomplicated design has segment retaining ring and mild steel silver plated (or graphite) gasket to aid disassembly and provide maximum bonnet seal
• Internal Disc Hanger – unique arrangement eliminates pin seal leakage and simplifies maintenance.
• The CNI tilting disc check valve uses gravity to rapidly close the disc upon reversal of flow.
• This short-arc coupled with the low pendulum effect achieved by pivoting the disc through a point near its center of gravity assures rapid closure.
