Hydrotek HB8-D1T-05-WB Automatic Battery-Operated Flush Valve (0.5 GPF Urinal)

The Hydrotek HB8-D1T-05-WB is a high-efficiency, sensor-activated concealed flush valve engineered for modern commercial restrooms that demand a combination of architectural security and extreme water conservation. This 0.5 GPF (1.9 LPF) urinal valve is designed for behind-the-wall installation and includes an integrated heavy-duty stainless steel wall box, providing an elite level of protection against vandalism and unauthorized tampering. Configured with a 3/4" inlet stop and a 3/4" top spud connection, this system is the definitive solution for LEED-certified buildings, educational institutions, and high-security government facilities.

Professional-Grade Engineering & Vandal Resistance

• Integrated Wall Box Security: The "WB" designation signifies the inclusion of a recessed, heavy-gauge stainless steel wall box enclosure. By housing the infrared sensor, flushing mechanism, and battery pack within this secure enclosure, the system is shielded from theft and physical impact. This configuration is essential for restrooms where fixture security is paramount to maintaining uptime and reducing facility costs.
• Precision Piston Technology: Hydrotek’s proprietary industrial-grade piston design offers a significant performance advantage over traditional diaphragm valves. The piston mechanism ensures a consistent 0.5 GPF flush regardless of water pressure fluctuations and is highly resistant to mineral deposits and debris—the leading causes of valve failure and constant running in commercial environments.
• Corrosion-Resistant Construction: The valve body is manufactured from high-quality brass with a corrosion-resistant finish. Combined with industrial-grade VSI silicone elastomer seals, the system is engineered to withstand the aggressive chemicals often found in municipal water supplies, including chlorine and chloramines.
• Top Spud Integration: While the valve remains concealed for security, the 3/4" top spud configuration allows for seamless integration with standard top-access high-efficiency urinal fixtures. This setup combines the safety of a concealed valve with the versatility of a traditional fixture interface.

Advanced Sensor & Logic Features

• High-Efficiency Water Conservation: At just 0.5 GPF, this valve reduces water consumption by 50% compared to standard 1.0 GPF models, making it a critical component for achieving water efficiency goals and LEED points.
• 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-D1T-05-WB is an ideal solution for retrofitting existing facilities where running electrical hardwiring is difficult or cost-prohibitive.
• 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 for users at all times.
• 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 trap seal to prevent sewer gases from entering the restroom environment.
• 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.
