Hydrotek HB8CT-16DF-WB Automatic Dual-Flush Flush Valve (1.6 / 1.0 GPF Closet)

The Hydrotek HB8CT-16DF-WB is an advanced, sensor-activated dual-flush system engineered for commercial facilities that require the highest levels of water conservation without sacrificing flushing power. This high-efficiency closet valve delivers a standard 1.6 GPF (6.0 LPF) flush for solids and a water-saving 1.0 GPF (3.8 LPF) flush for liquids, reducing overall water consumption by up to 30%. Designed for behind-the-wall installation and featuring an integrated stainless steel wall box, it provides maximum security against vandalism while maintaining a modern, streamlined restroom environment.

Professional-Grade Engineering & Vandal Resistance

• Integrated Wall Box Security: The "WB" designation signifies a heavy-gauge, recessed stainless steel wall box. By housing the infrared sensor, dual-flush logic, and mechanical components within this secure enclosure, the system is shielded from tampering, theft, and impact. This is the gold standard for high-security environments like correctional facilities, stadiums, and high-traffic public venues.
• Superior Piston Technology: Hydrotek’s industrial-grade piston design offers significant performance advantages over traditional diaphragm valves. The piston ensures highly accurate flush volumes (both 1.6 and 1.0 GPF) regardless of water pressure fluctuations and is exceptionally resistant to mineral deposits and debris—the primary causes of valve failure.
• Corrosion-Resistant Internals: Built with a high-quality brass valve body and industrial-grade VSI silicone elastomer seals, the system is engineered to withstand the aggressive effects of chlorine and chloramines found in modern municipal water supplies.
• Top Spud Integration: Configured for a 1-1/2" top spud connection and including a 1" inlet stop, this valve remains concealed for security while interfacing seamlessly with standard top-access closet fixtures.

Intelligent Dual-Flush Sensor Logic

• Automated Water Conservation: The sophisticated infrared sensor automatically determines the required flush volume based on the duration of the user's presence. This "smart" logic eliminates the need for user decision-making, ensuring water savings are achieved consistently.
• Touchless ADA Compliance: Provides a 100% hands-free experience, fulfilling all ADA accessibility requirements and significantly improving facility hygiene by eliminating common touchpoints and reducing cross-contamination.
• Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, the HB8CT-16DF-WB is the ideal solution for retrofitting facilities where hardwiring is difficult 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 toilet is always operational.
• Smart Self-Diagnostics: Includes integrated self-diagnostic capabilities and a manual reset function to simplify troubleshooting and streamline routine maintenance for facility staff.
