Product Details

  • Reinforced silicone seals
  • Next generation design for long life
  • Flexi hinge check valves have features to make them ideal for use with positive displacement and centrifugal blowers
  • They are designed for maximum air flow with minimal pressure loss, while providing positive reverse flow sealing at low flows and low backpressure without the need for springs
  • Valve life is extended because of three important Flexi-Hinge features
  • When fully closed the valve seal backing plates rest against the internal center hinge post without pinching the elastomer hinge or seal
  • When fully open the valve plates rest against a Teflon® covered stop to prevent the valve plates from fluttering
  • For maximum flex life and sealing performance, the silicone sealing member is reinforced with Nomex™ mesh
  • Replacement repair kits fit all valves
