Elastomer-Hinged Wafer-Style Check Valves


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.

Design features:




  • 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.
