Hydrotek HB8-D1B-0125-WB Automatic Battery-Operated Flush Valve (0.125 GPF Urinal)

The Hydrotek HB8-D1B-0125-WB represents the absolute pinnacle of ultra-high-efficiency (UHE) restroom technology, engineered specifically for facilities that demand the highest levels of water conservation and architectural security. Delivering a precision-calibrated 0.125 GPF (0.47 LPF)—often referred to as a "pint flush"—this system provides an 87.5% reduction in water usage compared to standard 1.0 GPF fixtures. Designed for behind-the-wall installation and featuring an integrated stainless steel wall box, it is the premier choice for LEED Platinum projects, high-security correctional facilities, and high-traffic public stadiums.

Professional-Grade Engineering & Vandal Resistance

• Integrated Wall Box Security: The "WB" designation signifies the inclusion of a heavy-gauge recessed stainless steel wall box. This enclosure houses the infrared sensor and mechanical flush components, shielding them from tampering, impact, and unauthorized adjustments. This configuration is critical for high-security environments where fixture integrity is paramount.
• Superior Piston Technology: Unlike traditional diaphragm-style valves, Hydrotek utilizes an industrial-grade piston mechanism. This design ensures highly accurate flush volumes even in buildings with fluctuating water pressures and is exceptionally resistant to mineral deposits and debris that often cause standard valves to fail or run continuously.
• Heavy-Duty Construction: Built with a high-quality brass valve body and industrial-grade VSI silicone elastomer seals, the system is engineered to withstand the harsh effects of chlorine, chloramines, and other chemicals found in modern municipal water supplies.
• Concealed Back Spud Interface: Designed for 3/4" back spud urinal fixtures, this behind-the-wall configuration eliminates exposed piping and electrical connections. This creates a streamlined, modern aesthetic while removing leverage points that could be targeted for vandalism.

Advanced Sensor & Logic Features

• Touchless ADA Compliance: The integrated infrared sensor provides a 100% hands-free experience, fulfilling all ADA accessibility requirements while significantly improving facility hygiene by eliminating common touchpoints and reducing cross-contamination.
• Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, the HB8-D1B-0125-WB is the perfect solution for facility retrofits where running hardwiring is cost-prohibitive or for new construction seeking simplified installation.
• True Mechanical Manual Override: Features a standard manual-mechanical override button that remains fully functional even in the event of battery exhaustion, ensuring the urinal remains operational at all times.
• Automated Hygiene (Sentinel) Flush: Includes a built-in 24-hour sentinel flush feature that automatically activates the valve during periods of low occupancy. This keeps the fixture’s trap seal primed to prevent the escape of sewer gases into the building.
• Smart Self-Diagnostics: The electronic system includes integrated self-diagnostic capabilities and a manual reset function to simplify troubleshooting and streamline routine maintenance for facility staff.
