Hydrotek HB8CMB-B1-05 High-Efficiency Sensor Urinal Flush Valve (Matte Black)

The Hydrotek HB8CMB-B1-05 is a high-performance, battery-operated flush valve that combines industrial-grade reliability with a striking architectural finish. Finished in a premium Matte Black, this valve is designed for upscale commercial restrooms where design-forward aesthetics are as critical as operational efficiency. Delivering a consistent 0.5 GPF (1.9 LPF), it provides a 50% water savings compared to standard 1.0 GPF units, offering a perfect balance between aggressive water conservation and a thorough, hygienic rinse for high-traffic facilities.

Precision Engineering & Durability

• Heavy-Duty Brass Construction: Manufactured from high-copper, low-zinc brass to ensure maximum resistance to dezincification and long-term structural integrity in demanding environments.
• Piston-Operated Precision: Features a superior, slow-closing piston mechanism that maintains accurate flush volumes and consistent cycle times, even in buildings with fluctuating municipal water pressure.
• Corrosion-Resistant Components: Equipped with industrial-grade VSI silicone elastomer piston seals, specifically engineered to resist the damaging effects of chlorine, chloramines, and chemical cleaners.
• Advanced Filtration: Includes a standard self-cleaning filtering system that protects the internal solenoid and piston from waterborne debris, significantly reducing the risk of clogging and extending maintenance intervals.

Advanced Operational Intelligence

• Battery-Powered Reliability: Powered by four (4) standard AA alkaline batteries, providing a seamless touchless solution for retrofits or high-end installations where hardwiring is not feasible. Includes an integrated low-battery indicator.
• Touchless ADA Compliance: The advanced infrared sensor offers a completely sanitary, "no-hands" experience, ensuring full compliance with ADA accessibility requirements while minimizing the spread of germs.
• Smart Self-Diagnostics: Features an integrated electronic system with self-diagnostics and a manual reset function to simplify troubleshooting and facility-wide management.
• Automated Hygiene (Sentinel Flush): Includes a built-in 36-hour sentinel flush feature to automatically activate the valve during periods of inactivity, preventing trap seal evaporation and sewer gas odors.
• True Mechanical Override: Equipped with a standard manual-mechanical override button, ensuring the urinal remains fully functional even in the event of battery exhaustion.
