Our patent pending, self-clearing Vortex Auto-Drain Valve allows gray water to flow from a lavatory or galley sink into the drain mast, while inhibiting airflow during sink operation. This design eliminates the familiar “hissing” noise created by air escaping the drain. Unlike competing products, this valve is designed to remain open, allowing the drain to function in high altitude or on the ground.
Features & benefits
- Proprietary, self-clearing design prevents clogging from debris like coffee grounds. This presents an advantage over competing products where clogging leads to eventual valve failure
- Constructed from lightweight, durable and chemical-resistant polymers; Ultem™ free
- Integrated backflow prevention valve that doesn’t stick in the closed or open position
- Designed to remain open when aircraft is unpressurized, allowing drainage while on ground
