Few things are more frustrating than valves that leak at startup! Now you can have a globe check valve that has true drip-tight closure.

Av-Tek’s SDX Sliding Disc Check Valve is the result of years of advanced engineering and study. This progressive design offers the latest technology specifically designed for use in water applications.

Standard silent check valves are metal seated and have an allowable leakage of 1 oz per inch of diameter per hour. With its modern features and high-grade materials, the SDX sliding disc check valve is bubble tight and will not have leakage. Av-Tek strives to bring unprecedented longevity and reliability to meet the critical service demands of a modern water structure. As such, we offer different spring options to ensure your valve performs in both high and low pressure lines, as well as high and low velocity applications.

With its modern features and high-grade materials, the SDX sliding disc check valve is bubble tight and will not have leakage due to the mechanically retained seat. This seat is retained by a 316 SST ring that is designed to be blow out proof.

Why Should You Use Av-Tek's SDX Sliding Disc Check Valve?

Sliding disc design

The SDX sliding disc check valve combines the technology of the silent check valve with Av-Tek’s DEX Double Eccentric Butterfly Valve to provide bubble tight shut-off in clean water applications.

Mechanically retained T-shaped resilient seat

Utilizing the same design and technology of our industry changing DEX Double Eccentric Butterfly Valves, the SDX is designed to resist high velocities. Other manufacturers machine an optional grove and hand press-fit o-rings to a resilient seat, but often they come loose under high flow conditions or after staying closed for a period of time.

316L SST welded body seat

Robotically welded SST seats are micro finished and polished. The chemical properties of the Nickel Chromium SST prevent corrosion between the seat and ductile iron body while preventing body seat separation and undercutting.

Certified zero leakage

Each SDX Check Valve undergoes unique testing and is Certified for Zero Leakage at the factory in accordance with EN and AWWA Standards.

Common applications:

  • Eliminates shock to prevent water hammer
  • Booster Pump Stations for potable water
  • Separation between two merging systems
