Elastomer-Hinged Wafer-Style Check Valves


US Valve's TECHNO line has been a leading supplier of high-quality check valves to the industry for many years. A large number of TECHNO products are presently in service, demonstrating a superior performance record.

 The TECHNO check valve design, combined with an extensive selection of materials, results in high performance and reliability for most liquid and gas applications.

The elastomer-hinged TECHNO wafer-style check valve offers compact design along with heavy-duty construction.

The scalloped body design ensures proper and easy alignment between mating gaskets and line flanges. It offers strength and reduces the need for expensive supports, expansion joints and foundations that may be necessary with a conventional check valve.

Our unique design, combined with years of experience, allows us to satisfy some of the most difficult applications.

Other configurations are available upon request.

TECHNO
            Elastomer-hinged Wafer-Style Check Valves



  • The stationary hinge-post and hinge-clamp design reduces wear to hinges, pins, valve seats, springs and the need for routine maintenance.
  • The valve plate design reduces travel from a fully open to fully closed position and provides complete metal-to-metal valve plate structural support, resulting in a non-slam, quick closure feature.
  • Our unique flexible elastomer seal provides final closure around the valve bore with continuous strength and durability to ensure prolonged cycle life, outwearing traditional metal-seated valves.

All dimensions are in inches.

For sizes 2" to 12", check valves with carbon steel, 316 SS or aluminum bodies are known as Style 5296. They are rated at 150 psi cold working pressure. Carbon steel and stainless steel have raised-face ends. Aluminum bodies have flat face ends.

Bodies are made from solid round material and do not have the scalloped edges like the 5118 which is produced from a casting. The outside diameter is made to fit within the bolting pattern of ASME 150# flanges.
