Hydrotek HB8CPB-B1-05 High-Efficiency Sensor Urinal Flush Valve (Polished Brass)

The Hydrotek HB8CPB-B1-05 is a professional-grade, battery-operated flush valve that bridges the gap between classic architectural elegance and modern high-efficiency performance. Finished in a premium Polished Brass, this unit provides a sophisticated, mirror-like aesthetic ideal for luxury hospitality, corporate executive suites, and historic restorations. Delivering a WaterSense-compliant 0.5 GPF (1.9 LPF), it ensures reliable, touchless operation while reducing water consumption by 50% compared to standard 1.0 GPF urinal valves.

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 and a lasting finish in high-traffic 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 VSI silicone elastomer piston seals, specifically engineered to remain unaffected by the corrosive effects of chlorine, chloramines, and ammonia.
• Internal Debris Protection: A standard self-cleaning filtering system protects the internal solenoid and piston from waterborne sediment and mineral buildup, extending maintenance cycles and protecting your investment.

Advanced Operational Intelligence

• Battery-Powered Independence: Operates on four (4) standard AA alkaline batteries, making it an ideal choice for retrofits or high-end installations where hardwiring is not feasible. Includes an integrated low-battery indicator.
• Touchless ADA Compliance: The advanced infrared sensor provides a completely sanitary, "no-hands" experience, ensuring full compliance with ADA accessibility guidelines 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.
