Hydrotek HB8D1B-025 Automatic Battery-Operated Flush Valve (0.25 GPF Urinal)
The Hydrotek HB8D1B-025 is an ultra-high-efficiency (UHE), battery-powered concealed flush valve designed for maximum water conservation and professional-grade performance. Engineered for behind-the-wall installations, this system is configured for a 3/4" back spud urinal and includes a matching 3/4" inlet stop. By delivering a precision-calibrated 0.25 GPF (0.9 LPF), this valve provides a 75% reduction in water usage compared to standard 1.0 GPF fixtures, making it a critical component for facilities aiming for peak LEED certification and sustainability.
Professional-Grade Engineering & Design
- Vandal-Resistant Concealed Installation: Specifically built for environments where aesthetics and security are paramount. By housing all mechanical and electronic components behind the wall, the HB8D1B-025 is protected from tampering and accidental damage, making it ideal for stadiums, schools, and high-traffic public facilities.
- Industrial Piston Accuracy: Unlike traditional diaphragm valves that can be prone to inconsistent flushing or premature failure due to sediment, Hydrotek’s superior piston technology ensures precise flush volumes. This design provides exceptional reliability across a wide range of water pressures.
- Corrosion-Resistant Construction: Manufactured with high-quality materials and industrial-grade VSI silicone elastomer seals, the valve is engineered to withstand the harsh effects of chlorine, chloramines, and other aggressive water treatments without degrading.
- Complete Installation Package: This model is supplied as a comprehensive kit, including the sensor-operated valve, a 3/4" inlet stop, and the necessary 3/4" 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 and significantly reducing the spread of germs in shared restroom environments.
- Battery-Powered Reliability: Powered by four (4) standard AA alkaline batteries, this valve is the perfect 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: Includes a built-in 24-hour sentinel flush feature that automatically activates the valve during periods of inactivity to maintain the trap seal and prevent the escape of sewer gas odors.
- Smart Self-Diagnostics: Features an integrated electronic system with self-diagnostics and a manual reset function to simplify troubleshooting and streamline routine facility-wide maintenance.
