Hydrotek HB-8000C-D2B-WB Automatic Battery-Operated Flush Valve (1.0 GPF Urinal)

The Hydrotek HB-8000C-D2B-WB is a heavy-duty, sensor-activated concealed flush valve engineered specifically for high-security and high-traffic commercial environments. This 1.0 GPF (3.8 LPF) urinal valve is designed for behind-the-wall installation and features an integrated stainless steel wall box, providing an elite level of protection against vandalism and tampering. Configured with a 1" inlet stop and a 1-1/4" back spud connection, this system is the definitive solution for stadiums, correctional facilities, and public transit hubs that require uncompromising durability and a clean, professional aesthetic.

Professional-Grade Engineering & Vandal Resistance

• Integrated Wall Box Security: The "WB" designation signifies the inclusion of a heavy-gauge recessed stainless steel wall box. By housing the infrared sensor and flushing mechanism within this secure enclosure, the system is shielded from theft, impact, and unauthorized adjustments. This configuration is essential for restrooms where fixture security is as important as performance.
• Precision Piston Technology: Hydrotek’s industrial-grade piston design offers a significant advantage over traditional diaphragm valves. The piston mechanism ensures a consistent 1.0 GPF flush regardless of water pressure fluctuations and is highly resistant to mineral deposits and debris, ensuring long-term reliability and reducing maintenance intervals.
• Durable 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 built to withstand the aggressive chemicals often found in municipal water supplies.
• Concealed 1-1/4" Back Spud Interface: Designed specifically for 1-1/4" back spud urinal fixtures, this configuration keeps all plumbing connections behind the wall. This eliminates exposed piping that could be used as a leverage point for vandalism and creates a modern, streamlined user environment.

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 reducing cross-contamination.
• Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, the HB-8000C-D2B-WB is an ideal solution for retrofitting existing facilities where running electrical hardwiring is cost-prohibitive.
• True Mechanical Manual Override: Features a standard manual-mechanical override button that remains fully functional even in the event of battery failure, ensuring the urinal is always operational for users.
• 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.
• 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.
