Hydrotek HB8D2B-025 Automatic Battery-Operated Flush Valve (0.25 GPF Urinal)
The Hydrotek HB8D2B-025 is an ultra-high-efficiency (UHE) concealed flush valve specifically engineered for maximum water conservation and professional-grade durability. Designed for behind-the-wall installations, this system is configured for a 1-1/4" back spud urinal and includes a heavy-duty 1" inlet stop. Delivering a precision-calibrated 0.25 GPF (0.9 LPF), this valve reduces water consumption by 75% compared to standard 1.0 GPF fixtures, making it an essential component for facilities striving for elite LEED certification and sustainable facility management.
Professional-Grade Engineering & Design
- Vandal-Resistant Concealed Installation: Specifically built for high-traffic environments where restroom aesthetics and security are critical. By housing the mechanical and electronic components behind the wall, the HB8D2B-025 is protected from tampering, vandalism, and accidental damage, making it ideal for stadiums, airports, and schools.
- Precision Piston Technology: Hydrotek’s industrial-grade piston mechanism provides a significant advantage over traditional diaphragm valves. It ensures highly accurate flush volumes even in buildings with fluctuating water pressures and is exceptionally resistant to mineral deposits and debris that often cause common valve failures.
- Corrosion-Resistant Internals: Manufactured with high-quality materials and industrial-grade VSI silicone elastomer seals, the unit is engineered 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 provides a 100% hands-free experience, fulfilling all ADA accessibility requirements and significantly improving sanitary conditions by reducing cross-contamination in shared restrooms.
- Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, this valve is the perfect solution for facility retrofits where running electrical 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 in the event of battery exhaustion.
- Automated Hygiene (Sentinel) Flush: Features a built-in 24-hour sentinel flush that automatically activates the valve during periods of low occupancy. This keeps the fixture’s trap seal primed to prevent 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.
