Hydrotek HB8CMB-B1-0125 Ultra-High Efficiency Sensor Urinal Flush Valve (Matte Black)

The Hydrotek HB8CMB-B1-0125 represents the pinnacle of sustainable restroom technology paired with high-concept architectural design. Finished in a sophisticated Matte Black, this battery-operated flush valve is the definitive choice for modern commercial environments—such as creative offices, luxury lounges, and high-end hospitality venues—where a bold, non-reflective aesthetic is required. Delivering an ultra-high efficiency 0.125 GPF (0.5 LPF), this unit provides an 87% reduction in water usage compared to standard valves, making it an essential component for LEED-certified projects and advanced green building initiatives.

Precision Engineering & Durability

• Heavy-Duty Brass Construction: Cast from high-copper, low-zinc brass to ensure maximum resistance to dezincification, maintaining structural integrity in high-use, demanding commercial settings.
• Advanced Piston Mechanism: Features a superior, slow-closing piston flushing mechanism that guarantees consistent cycle times and accurate flush volumes, even during municipal water pressure fluctuations.
• Chemical-Resistant Seals: Equipped with industrial-grade VSI silicone elastomer piston seals, specifically formulated to withstand the corrosive effects of chlorine, chloramines, and ammonia.
• Debris Management System: Includes a standard self-cleaning filtering system that protects the internal solenoid and piston from waterborne sediment, significantly reducing maintenance and protecting the valve's service life.

Advanced Operational Intelligence

• Battery-Powered Independence: Operates on four (4) standard AA alkaline batteries, offering a seamless touchless solution for retrofits or high-design installations where hardwiring is not preferred. Includes an integrated low-battery indicator.
• Touchless ADA Compliance: The advanced infrared sensor provides a completely sanitary, "no-hands" experience, ensuring full compliance with ADA accessibility requirements while minimizing cross-contamination.
• Smart Self-Diagnostics: Features an electronic system with integrated self-diagnostics and a manual reset function to simplify troubleshooting for facility managers.
• Automated Hygiene (Sentinel Flush): Includes a built-in 36-hour sentinel flush feature to automatically activate the valve during periods of inactivity to maintain the trap seal and prevent 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 failure.

Technical Specifications & Installation

• Fixture Compatibility: Designed for exposed installation on 3/4" top spud urinal fixtures.
• Standard Connections: Includes a 3/4" I.P.S. angle stop valve with a vandal-resistant cap and a 3/4" top spud coupling.
• Operating Range: Functions effectively across a wide operational pressure range of 10–125 PSI.
• Field Adaptability: Features an adjustable tailpiece to accommodate field variations and is adaptable for left-hand rough-in configurations.
