Hydrotek HB8CBN-128 High-Efficiency Sensor Flush Valve (Brushed Nickel)

The Hydrotek HB8CBN-128 is a commercial-grade, battery-operated toilet flush valve that merges high-efficiency performance with a refined aesthetic. Finished in a premium Brushed Nickel, this unit provides a sophisticated, modern alternative to standard chrome while delivering a WaterSense-compliant 1.28 GPF (4.8 LPF). Designed for high-traffic environments, it ensures reliable, touchless operation that meets the most demanding durability and sanitation standards.

Precision Engineering & Durability

• Heavy-Duty Brass Construction: Cast from high-copper, low-zinc brass to ensure maximum resistance to dezincification, providing long-term structural integrity.
• Superior Piston Mechanism: Features a slow-closing piston flushing mechanism that maintains consistent cycle times and accurate flush volumes, even under varying water pressures.
• Chemical-Resistant Seals: Equipped with VSI silicone elastomer piston seals, specifically engineered to withstand the degrading effects of chlorine, chloramines, and ammonia.
• Internal Debris Management: A standard self-cleaning filtering system protects the internal solenoid and piston from waterborne sediment, reducing maintenance requirements.

Advanced Operational Intelligence

• Battery-Powered Independence: Operates on four (4) standard AA alkaline batteries, making it an ideal solution for retrofits where hardwiring is not feasible. Includes a low-battery indicator for proactive maintenance.
• Touchless ADA Compliance: The advanced infrared sensor provides a completely sanitary, "no-hands" experience, ensuring full compliance with ADA accessibility guidelines.
• Smart Self-Diagnostics: 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 that automatically activates the valve during periods of inactivity to maintain the trap seal.
• True Mechanical Override: Equipped with a standard manual-mechanical override button, ensuring the fixture remains fully operational even in the event of battery failure.

Technical Specifications & Installation

• Fixture Type: 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: Engineered to function effectively across a wide operational range of 10–125 PSI.
• Rough-In Flexibility: Features an adjustable tailpiece to accommodate field variations and is adaptable for left-hand rough-in configurations.
