Hydrotek HB8CBN-16DF Dual-Flush Sensor Flush Valve (Brushed Nickel)

The Hydrotek HB8CBN-16DF is a high-performance, battery-operated dual-flush valve designed for commercial facilities that prioritize both traditional flushing power and modern water conservation. Finished in an elegant Brushed Nickel, this unit provides a high-end architectural look while utilizing intelligent sensor technology to reduce water consumption. By automatically toggling between a full 1.6 GPF flush and a water-saving 1.0 GPF flush based on user dwell time, this valve ensures optimal performance for water closet fixtures while supporting sustainability goals.

Precision Engineering & Durability

• Heavy-Duty Brass Construction: Cast from high-copper, low-zinc brass to provide maximum resistance to dezincification and ensure long-term structural integrity in high-use environments.
• Reliable Piston Mechanism: Features a superior, slow-closing piston flushing mechanism that maintains consistent cycle times and accurate flush volumes regardless of water pressure fluctuations.
• Chemical-Resistant Internal Components: Equipped with 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 1.6 GPF flush for solid waste (user present for 60 seconds or more).
• Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, making it the perfect choice for retrofits where hardwiring is difficult or unavailable. Includes a low-battery indicator light.
• Touchless ADA Compliance: The 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 facility troubleshooting and maintenance.
• Automatic Hygiene Flush (Sentinel Flush): Includes a built-in 36-hour sentinel flush feature to automatically activate the valve during periods of inactivity, maintaining the trap seal.
• Manual Mechanical Override: Equipped with a standard manual-mechanical override button, ensuring the toilet remains fully functional even during 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.
• Field Adaptability: Features an adjustable tailpiece to accommodate field variations and is adaptable for left-hand rough-in configurations.
