Hydrotek HB8D1B-0125 Automatic Battery-Operated Flush Valve (0.125 GPF Urinal)
The Hydrotek HB8D1B-0125 represents the absolute pinnacle of water conservation technology for modern commercial restrooms. Engineered for behind-the-wall installations, this ultra-high-efficiency (UHE) concealed flush valve is configured for a 3/4" back spud urinal and includes a matching 3/4" inlet stop. By delivering a precision-calibrated 0.125 GPF (0.47 LPF)—often referred to as a "pint" flush—this valve provides an extraordinary 87.5% reduction in water usage compared to standard 1.0 GPF fixtures. It is the definitive choice for facilities seeking the highest LEED certification points and the lowest possible utility overhead.
Professional-Grade Engineering & Design
- Vandal-Resistant Concealed Installation: Specifically designed for high-security environments and architecturally clean spaces. By housing all mechanical and electronic components behind the wall, the HB8D1B-0125 is protected from tampering and accidental damage, making it ideal for stadiums, airports, and high-traffic public facilities.
- Superior Piston Technology: Unlike traditional diaphragm-based valves that can fail due to mineral buildup or pressure drops, Hydrotek utilizes an industrial-grade piston mechanism. This design ensures consistent flush volumes and peak performance across a wide range of water pressures.
- Heavy-Duty, Corrosion-Resistant Construction: Manufactured with premium materials and industrial-grade VSI silicone elastomer seals, the unit is engineered to resist the corrosive effects of chlorine, chloramines, and other aggressive water treatments found in modern municipal supplies.
- Complete Concealed 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 provides a 100% hands-free experience, fulfilling all ADA accessibility requirements while significantly reducing cross-contamination in shared restroom environments.
- Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, this valve is an ideal solution for retrofitting facilities where electrical hardwiring is unavailable 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. This maintains the fixture’s trap seal, preventing 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 maintenance.
