Hydrotek HB-8000C-CB-WB Automatic Battery-Operated Flush Valve (1.6 GPF Closet)

The Hydrotek HB-8000C-CB-WB is a heavy-duty, sensor-operated concealed flush valve system specifically engineered for high-security and high-traffic commercial environments. This 1.6 GPF (6.0 LPF) closet valve is designed for behind-the-wall installation and comes integrated with a stainless steel wall box, providing the ultimate defense against vandalism while maintaining a clean, professional restroom aesthetic. Configured for a 1-1/2" back spud connection and including a 1" inlet stop, this system is the definitive solution for stadiums, correctional facilities, and public transit hubs.

Professional-Grade Engineering & Vandal Resistance

• Integrated Wall Box Security: The "WB" designation signifies the inclusion of a heavy-gauge stainless steel wall box. By mounting the sensor and flush mechanism within this recessed enclosure, the components are protected from tampering, theft, and physical impact.
• Precision Piston Technology: Hydrotek’s industrial piston design offers superior performance over traditional diaphragm valves. The piston mechanism ensures a consistent 1.6 GPF flush regardless of water pressure fluctuations and is highly resistant to mineral buildup and debris, significantly reducing long-term maintenance costs.
• Durable Construction: The valve body is manufactured from high-quality brass with a corrosion-resistant finish. Paired with industrial-grade VSI silicone elastomer seals, the system is built to withstand the aggressive chemical treatments common in municipal water supplies.
• Concealed Back Spud Interface: Designed specifically for 1-1/2" back spud closets, this configuration keeps all plumbing connections behind the wall, ensuring a streamlined user environment and eliminating exposed piping that could be used as a leverage point 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 promoting a more hygienic, germ-free restroom environment.
• Battery-Powered Reliability: Powered by four (4) standard AA alkaline batteries, the HB-8000C-CB-WB is ideal for both new construction and retrofitting existing facilities where hardwiring is difficult or cost-prohibitive.
• True Mechanical Manual Override: Features a standard manual-mechanical override button that remains functional even in the event of battery failure, ensuring the fixture never goes out of service.
• Automated Hygiene (Sentinel) Flush: Includes a built-in 24-hour sentinel flush feature that automatically activates the valve during periods of inactivity. This ensures the trap seal remains primed and prevents sewer gases from entering the facility.
• Self-Diagnostic Electronics: The smart electronic system includes integrated self-diagnostics and a manual reset function to simplify troubleshooting for facility maintenance staff.
