Pressure Seal Tilting Disk Check Valve
Description
Overview
Pressure Seal Tilting Disc Valves close rapidly with an exceptionally tight shutoff, needing only to swing 45⁰ to fully open and close.
- 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.
