How it works

.

Find the right AS-H Coplastix® flap valve for your application:

  • Circular flap valves from 4" – 24" (102 mm – 610 mm) are constructed solely of Coplastix or rubber materials and may be either wall-mounted or pipe-mounted.
  • Rectangular flap valves consist of a Coplastix or rubber door and select steel frame materials.
  • Flexible flap valves employ a specially developed, externally supported rubber compound for the door. Rigid and rubber flap valves are available in many sizes from 24" – 144" (610 mm – 3,658 mm).

Features and benefits

  • Corrosion-resistant
  • Gate exercising not required
  • 10 times less friction than metal-to-metal gates
  • Disc and seal design prevents gate seizure
  • Half leakage rates of other conventional gates
  • 10 year warranty so you can install with confidence

About Coplastix®

The Coplastix range was designed to exceed all other gate types in longevity without the regular maintenance or exercising. Coplastix materials are lighter, easier to install and extremely durable.

Transform corroded, inoperable valves into smooth operating, corrosion-resistant valves that help put your fluid control system back in operating condition.
