IRX-B 70/71 Series

The IRX B is a compact, integrated ball and check valve designed to deliver high-flow performance while reducing system footprint and complexity. By combining isolation and backflow prevention into a single unit, the IRX B eliminates the need for separate valves and additional piping. Built on the proven elastomer hinge check valve design, the IRX B maintains high Cv and low pressure drop while simplifying system layout and improving installation efficiency.

The IRX‑B integrates ball valve shutoff and check valve functionality into a single, internally retained design. This reduces system size, simplifies installation, and maintains the proven performance of elastomer hinge technology. Available in 1" through 6" across a wide range of end connections and materials.

  • Integrated valve design: Combines ball valve shutoff and check valve backflow prevention in a single unit, reducing components and simplifying system design.
  • Reduced footprint and installation cost: Eliminates the need for separate valves and additional piping, lowering installation cost, minimizing connection points, and reducing overall space requirements.
  • Proven elastomer hinge performance: Maintains high-flow, low-pressure-drop performance with maximum Cv and no restrictive seat to impede flow.
  • Flexible connection and material options: Available in Tri-Clamp, Wafer, Flanged, Grooved, MNPT, Barb, and custom configurations with body materials in 316SS, aluminum, and ductile iron, disc options in 316SS or aluminum, and seals including Buna, EPDM, PTFE, Silicone, and Viton.
  • Durable internal components: 316 stainless steel ball and spring materials provide reliability and long service life in demanding applications.
  • Designed for constrained, high-performance systems: Ideal for compressed air, vacuum, blower, industrial gas, food processing, and chemical service where compact layout and efficiency are critical.
