In high-traffic restrooms, the flush valve is the most-touched — or ideally, never-touched — piece of hardware in the room. The Amadora concealed sensor flush valve removes contact from the equation entirely. An infrared sensor detects each use and triggers the flush automatically, keeping the fixture clean, the restroom odor-free, and the water consumption well below conventional manual valves.

Why Facility Managers Choose the Amadora

• Fully touch-free operation — infrared sensor activates flushing without physical contact, reducing cross-contamination and vandalism risk
• Intelligent water management — onboard microprocessor monitors traffic patterns and adjusts flush volume accordingly, averaging 1.2–4L per cycle
• Pre-flush and main flush cycles — dual-cycle flushing delivers consistent hygiene performance at pressures from 40 to 110 psi
• Low operating cost — runs on DC 6V with minimal standby draw; batteries rated for up to 2 years at 200 flush cycles per day
• Concealed rectangular housing — stainless steel finish sits flush with the wall for a clean, tamper-resistant appearance suited to commercial interiors
• Serviceable in the field — internal water-regulating valves and a strainer are accessible for routine adjustments and cleaning without full removal

Right For

The Amadora is specified for commercial restrooms where hygiene compliance, water efficiency, and low maintenance overhead are the primary requirements — office buildings, hospitality venues, healthcare facilities, schools, and high-traffic public restrooms. It also fits residential applications where touchless convenience is a priority.

Installation and ongoing maintenance should be performed by a licensed plumber to ensure code compliance and warranty coverage.
