The Silent Check Valve is engineered for applications where silent operation and cost efficiency are critical. Its short linear stroke and spring return action combine to close the valve prior to flow reversal, effectively eliminating shock and water hammer associated with sudden stoppage of reverse flow.

• Widely used in water supply and drainage, fire protection, HVAC, industrial and other systems
• Expanded Body design provides full flow area for optimal performance
• Double guided disc prevents vibrations and wear for extended service life
• Resilient Seat available for zero leakage applications
