Hydrotek HB8CBN-128DF Dual-Flush Sensor Flush Valve (Brushed Nickel)

The Hydrotek HB8CBN-128DF is an advanced, battery-operated dual-flush valve that represents the pinnacle of water conservation and modern restroom design. Finished in a premium Brushed Nickel, this unit offers a sophisticated architectural appearance while providing a dynamic flushing solution for high-traffic commercial environments. By automatically selecting between a full 1.28 GPF flush and a reduced 1.0 GPF flush based on the duration of user presence, this valve maximizes water efficiency without compromising fixture performance or hygiene.

Precision Engineering & Durability

• Heavy-Duty Brass Construction: Cast from high-copper, low-zinc brass to provide maximum resistance to dezincification, ensuring long-term structural integrity in demanding environments.
• High-Performance Piston Mechanism: Features a superior, slow-closing piston flushing mechanism designed for consistent cycle times and accurate flush volumes across a wide pressure range.
• Industrial-Grade Seals: Equipped with VSI silicone elastomer piston seals, specifically engineered to remain unaffected by chlorine, chloramines, and ammonia.
• Internal Debris Protection: Includes a standard self-cleaning filtering system that protects the solenoid and piston from waterborne sediment and mineral buildup.

Advanced Operational Intelligence

• Smart Dual-Flush Technology: Intelligently 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 Reliability: Operates on four (4) standard AA alkaline batteries, making it an ideal choice for retrofits where hardwiring is unavailable. Includes a low-battery indicator for proactive maintenance.
• Touchless ADA Compliance: The advanced infrared sensor provides a sanitary, "no-hands" experience, significantly reducing the risk of cross-contamination.
• Self-Diagnostic Electronics: Features an integrated electronic system with self-diagnostics and a manual reset function to simplify troubleshooting.
• Automated Hygiene (Sentinel Flush): Includes a built-in 36-hour sentinel flush feature to automatically clear the fixture during periods of inactivity and maintain the trap seal.
• Manual Mechanical Override: Equipped with a standard manual-mechanical override button to ensure the fixture remains fully functional during battery failure.

Technical Specifications & Installation

• Fixture Compatibility: 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.
• Pressure Range: Functions effectively across an operational range of 10–125 PSI.
• Field Adaptability: Features an adjustable tailpiece to accommodate field variations and is adaptable for left-hand rough-ins.
