The valve operates using flexible rubber flaps that open with forward flow pressure and automatically seal against backflow using elastic force and reverse pressure.
Rubber flaps resist entanglement from debris, hair, and sediment common in wastewater systems.
Elastic closure eliminates metal-on-metal contact noise during backflow prevention.
No rotating shafts or complex moving parts reduces maintenance requirements and downtime.
