Hydrotek HB8CMB-16DF Dual-Flush Sensor Flush Valve (Matte Black)

The Hydrotek HB8CMB-16DF is an elite, battery-operated dual-flush valve designed for high-end commercial environments where bold, contemporary aesthetics meet high-performance water management. Finished in a premium Matte Black, this valve provides a striking, modern look for luxury hotels, executive restrooms, and boutique retail spaces. By intelligently delivering either a full 1.6 GPF flush or a water-conserving 1.0 GPF flush based on user dwell time, this unit ensures a powerful performance for solid waste while significantly reducing water consumption for liquid waste.

Precision Engineering & Durability

• Heavy-Duty Brass Construction: Cast from high-copper, low-zinc brass to provide maximum resistance to dezincification, ensuring the unit remains structurally sound and the finish stays pristine in high-traffic restrooms.
• Superior Piston Mechanism: Features a high-performance, slow-closing piston flushing mechanism that ensures consistent cycle times and accurate flush volumes, even during municipal water pressure fluctuations.
• Chemical-Resistant Seals: Equipped with industrial-grade VSI silicone elastomer piston seals, specifically formulated to withstand the corrosive 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, reducing maintenance needs and extending the valve’s life.

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: Operates on four (4) standard AA alkaline batteries, providing a seamless touchless solution for retrofits or high-design installations where hardwiring is not preferred. Includes a low-battery indicator.
• Touchless ADA Compliance: The advanced infrared sensor offers a sanitary, "no-hands" experience, ensuring full compliance with ADA accessibility requirements while minimizing cross-contamination.
• Smart Self-Diagnostics: Features an integrated electronic system with self-diagnostics and a manual reset function to simplify facility troubleshooting and management.
• 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.
• Field Adaptability: Features an adjustable tailpiece to accommodate field variations and is adaptable for left-hand rough-in configurations.
