Hydrotek HB8D2B-0125 Automatic Battery-Operated Flush Valve (0.125 GPF Urinal)
The Hydrotek HB8D2B-0125 represents the ultimate standard in high-performance water conservation for commercial restrooms. Engineered for behind-the-wall installations, this ultra-high-efficiency (UHE) concealed flush valve is configured for a 1-1/4" back spud urinal and includes a heavy-duty 1" inlet stop. Delivering a precision-calibrated 0.125 GPF (0.47 LPF)—the industry-leading "pint" flush—this valve provides an 87.5% reduction in water consumption compared to standard 1.0 GPF models. It is the premier choice for facilities targeting the highest LEED certification levels and seeking to drastically lower utility overhead.
Professional-Grade Engineering & Design
- Vandal-Resistant Concealed Installation: Specifically designed for high-traffic environments where both aesthetics and security are critical. By housing all mechanical and electronic components behind the wall, the unit is shielded from tampering and accidental damage, making it ideal for stadiums, transit hubs, and educational institutions.
- Precision Piston Technology: Unlike traditional diaphragm valves that can be prone to inconsistent flushing or failure due to sediment, Hydrotek’s industrial-grade piston mechanism ensures precise flush volumes. This design provides exceptional reliability and longevity even in buildings with fluctuating water pressures.
- Heavy-Duty, Corrosion-Resistant Build: Constructed from high-quality brass and featuring industrial-grade VSI silicone elastomer seals, this valve is built to withstand the harsh effects of chlorine, chloramines, and other chemicals found in modern municipal water supplies.
- Comprehensive Concealed Kit: This model is supplied as a complete installation package, including the sensor-operated valve, a 1" inlet stop, and the necessary 1-1/4" back spud connection for a seamless concealed installation.
Advanced Sensor & Logic Features
- Touchless ADA Compliance: The integrated infrared sensor offers a 100% hands-free experience, fulfilling all ADA accessibility requirements while significantly improving restroom hygiene by eliminating common touchpoints.
- Battery-Powered Reliability: Powered by four (4) standard AA alkaline batteries, this valve is an ideal solution for retrofitting facilities where hardwiring is not feasible or would be cost-prohibitive.
- True Mechanical Manual Override: Equipped with a standard manual-mechanical override button, ensuring the urinal remains fully functional and can be flushed manually even if the batteries are completely exhausted.
- Automated Hygiene (Sentinel) Flush: Features a built-in 24-hour sentinel flush that automatically activates the valve during periods of inactivity. This maintains the fixture’s trap seal, preventing the escape of sewer gas odors.
- Smart Self-Diagnostics: The electronic system includes integrated self-diagnostic capabilities and a manual reset function to simplify troubleshooting and streamline routine facility-wide maintenance.
