Hydrotek HB8-B1-0375 High-Efficiency Sensor Urinal Flush Valve (0.375 GPF)

The Hydrotek HB8-B1-0375 is a precision-engineered, battery-operated flush valve designed to maximize water conservation without compromising fixture hygiene. Delivering a specialized 0.375 GPF (1.4 LPF), this unit provides a 62.5% reduction in water consumption compared to standard 1.0 GPF valves. It is an ideal solution for LEED-certified projects, high-traffic commercial facilities, and municipal buildings looking to achieve aggressive sustainability goals while maintaining the performance of their urinal fixtures.

Precision Engineering & Industrial Durability

• Heavy-Duty Brass Construction: Built from high-copper, low-zinc brass alloy to provide maximum resistance to dezincification and ensure long-term structural integrity in demanding environments.
• Reliable Piston Mechanism: Utilizes a superior, slow-closing piston flushing mechanism that maintains accurate flush volumes and consistent cycle times, even under fluctuating municipal water pressures.
• Chemical-Resistant Seals: Equipped with industrial-grade VSI silicone elastomer piston seals, specifically formulated to withstand the harsh effects of chlorine, chloramines, and ammonia common in water treatment.
• Integrated Debris Management: Features a standard self-cleaning filtering system that protects the internal solenoid and piston from waterborne sediment and mineral buildup, significantly reducing maintenance requirements.

Advanced Operational Intelligence

• Battery-Powered Independence: Operates on four (4) standard AA alkaline batteries, making it an ideal choice for retrofits where hardwiring is not present. Includes an integrated low-battery indicator to ensure uninterrupted service.
• Touchless ADA Compliance: The advanced infrared sensor provides a completely sanitary, "no-hands" user experience, meeting all ADA accessibility requirements and minimizing the spread of germs in the restroom.
• 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. This automatically activates 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: Engineered to function 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.
