The TECMA Double Duck-Bill Valve is a high-tech backflow prevention device specifically designed for onboard black water disposal systems. Its flexible, duckbill-shaped flapper design provides an impenetrable barrier against liquid backflow and gaseous emissions.

The Double Safety Principle:

Unlike standard single-flap valves, this model uses two valves mounted in series. This double-valve configuration increases safety: even if debris obstructs the closure of the first flapper, the second ensures a complete seal of the system.

Self-Adaptive Operation:

  • Dynamic Opening: Under the pressure of the maceration pump, the flexible flapper flaps open to allow waste to pass through without any obstruction.
  • Instant Closure: As soon as the pressure stops or reverses, the high-resistance elastomer lips seal tightly, instantly preventing any backflow into the toilet bowl.
  • Durability and Comfort: Made from a material resistant to treatment chemicals and marine effluents, this valve maintains its flexibility and effectiveness over the long term, guaranteeing a clean and odor-free environment in your cabins.
