Hydrotek HB8CMB-B1-025 High-Efficiency Sensor Urinal Flush Valve (Matte Black)

The Hydrotek HB8CMB-B1-025 is an elite, battery-operated flush valve that seamlessly integrates bold architectural style with rigorous water conservation standards. Finished in a premium, non-reflective Matte Black, this unit is the definitive selection for high-concept commercial restrooms, luxury hospitality venues, and contemporary corporate environments. Delivering a precision-engineered 0.25 GPF (0.9 LPF), it provides a 75% reduction in water usage compared to standard 1.0 GPF valves, making it a critical asset for facilities pursuing LEED certification and advanced sustainability goals.

Precision Engineering & Durability

• Heavy-Duty Brass Construction: Cast from high-copper, low-zinc brass to ensure maximum resistance to dezincification, maintaining long-term structural integrity in high-traffic, 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 range of water pressures.
• Industrial-Grade Seals: Equipped with chemical-resistant VSI silicone elastomer piston seals, specifically engineered to withstand the corrosive effects of chlorine, chloramines, and ammonia.
• Debris Protection System: Includes a standard self-cleaning filtering system that protects the internal solenoid and piston from waterborne sediment and mineral buildup, extending maintenance intervals.

Advanced Operational Intelligence

• Battery-Powered Independence: Operates on four (4) standard AA alkaline batteries, providing a seamless touchless solution for retrofits or high-end installations where hardwiring is not preferred. Includes an integrated low-battery indicator.
• Touchless ADA Compliance: The advanced infrared sensor offers a completely 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 troubleshooting and facility management.
• Automated Hygiene (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 and prevent sewer odors.
• True Mechanical Override: Equipped with a standard manual-mechanical override button, ensuring the urinal remains fully functional even in the event of battery failure.

Technical Specifications & Installation

• Fixture Compatibility: Designed for exposed installation on 3/4" top spud urinal fixtures.
• Standard Connections: Includes a 3/4" I.P.S. angle stop valve with a vandal-resistant cap and a 3/4" 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.
