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.
