Hydrotek HB8CPB-B1-0125 Ultra-High Efficiency Sensor Urinal Flush Valve (Polished Brass)

The Hydrotek HB8CPB-B1-0125 represents the ultimate intersection of traditional luxury and industry-leading water conservation. Finished in a brilliant, mirror-like Polished Brass, this battery-operated flush valve is engineered for high-profile commercial environments—such as boutique hotels, historic restorations, and executive suites—where architectural excellence is a priority. Delivering an ultra-high efficiency 0.125 GPF (0.5 LPF), it reduces water consumption by 87% compared to standard 1.0 GPF valves, making it an essential component for LEED-certified projects and advanced green building initiatives.

Precision Engineering & Durability

• Heavy-Duty Brass Construction: Cast from high-copper, low-zinc brass to provide maximum resistance to dezincification, ensuring the valve maintains its structural integrity and finish in demanding commercial settings.
• Advanced Piston Mechanism: Features a superior, slow-closing piston flushing mechanism that ensures consistent cycle times and accurate flush volumes, even under fluctuating water pressures.
• Chemical-Resistant Seals: Equipped with industrial-grade VSI silicone elastomer piston seals, specifically formulated to resist the corrosive effects of chlorine, chloramines, and ammonia found in municipal water.
• Debris Management System: Includes a standard self-cleaning filtering system that protects the internal solenoid and piston from waterborne sediment, significantly reducing maintenance requirements.

Advanced Operational Intelligence

• Battery-Powered Independence: Operates on four (4) standard AA alkaline batteries, providing a seamless touchless solution for retrofits or luxury installations where hardwiring is not feasible. 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 the risk of cross-contamination.
• Smart Self-Diagnostics: Features an electronic system with integrated self-diagnostics and a manual reset function to simplify troubleshooting for facility managers.
• 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 gas 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.
