Hydrotek HB8CPB-128DF Dual-Flush Sensor Flush Valve (Polished Brass)

The Hydrotek HB8CPB-128DF represents the pinnacle of sustainable luxury in commercial restroom technology. This battery-operated dual-flush valve combines a striking Polished Brass finish with high-precision intelligence to deliver a versatile water-saving solution. By automatically alternating between a 1.28 GPF full flush and a 1.0 GPF reduced flush based on user dwell time, this valve maximizes water efficiency in high-profile hospitality, boutique, and corporate environments without compromising on aesthetic excellence.

Precision Engineering & Durability

• Heavy-Duty Brass Construction: Cast from high-copper, low-zinc brass to ensure maximum resistance to dezincification and long-term structural integrity in high-use commercial settings.
• Superior Piston Mechanism: Features a high-performance, slow-closing piston flushing mechanism that maintains consistent cycle times and accurate flush volumes regardless of water pressure fluctuations.
• Chemical-Resistant Seals: Equipped with industrial-grade VSI silicone elastomer piston seals, specifically formulated to withstand the harsh effects of chlorine, chloramines, and ammonia.
• Integrated Debris Protection: Includes a standard self-cleaning filtering system that protects the internal solenoid and piston from waterborne sediment and mineral buildup.

Advanced Operational Intelligence

• Intelligent Dual-Flush Logic: Automatically delivers a 1.0 GPF flush for liquid waste (user present for less than 60 seconds) and a 1.28 GPF flush for solid waste (user present for 60 seconds or more).
• Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, providing a seamless touchless solution for retrofits or high-end installations. Includes a low-battery indicator.
• Touchless ADA Compliance: The advanced infrared sensor provides a sanitary, "no-hands" experience, significantly reducing cross-contamination and meeting all ADA accessibility requirements.
• Smart Self-Diagnostics: Features an integrated electronic system with self-diagnostics and a manual reset function to simplify maintenance and troubleshooting.
• Automatic Hygiene Flush (Sentinel Flush): Includes a built-in 36-hour sentinel flush feature to automatically activate the valve during periods of inactivity to maintain the trap seal.
• True Mechanical Override: Equipped with a standard manual-mechanical override button, ensuring the toilet remains fully functional even in the event of battery failure.

Technical Specifications & Installation

• Mounting Configuration: Designed for exposed installation on 1-1/2" top spud water closet (toilet) fixtures.
• Standard Connections: Includes a 1" I.P.S. angle stop valve with a vandal-resistant cap and a 1-1/2" top spud coupling.
• Operating Range: Functions effectively across a wide operational pressure range of 10–125 PSI.
