The Silent Check Valve is the preferred choice in applications where silent operation and cost are of major concern. Its short linear stroke and spring return action combine to close the valve prior to flow reversal which effectively eliminates the shock and water hammer normally associated with the sudden stoppage of a reverse flow.
  • Silent Operation - fast closure to prevent check valve slam water hammer

  • Precision metal-to-metal seating

  • Expanded Body - provides full flow area

  • Double guided disc - prevents vibrations and wear

  • Resilient Seat - available for zero leakage
