Hydrotek HB8-D1T-0125-WB Automatic Battery-Operated Flush Valve (0.125 GPF Urinal)

The Hydrotek HB8-D1T-0125-WB is an ultra-high-efficiency (UHE), sensor-activated concealed flush valve specifically engineered for commercial environments prioritizing extreme water conservation and maximum security. This 0.125 GPF (0.47 LPF) urinal valve—often referred to as a "pint" flush—provides an 87.5% reduction in water usage compared to standard 1.0 GPF fixtures. Designed for behind-the-wall installation and featuring an integrated heavy-duty stainless steel wall box, it delivers a vandal-proof solution that is essential for LEED Platinum projects, high-traffic transit hubs, and high-security government facilities.

Professional-Grade Engineering & Vandal Resistance

• Integrated Wall Box Security: The "WB" designation signifies a recessed, heavy-gauge stainless steel wall box. By housing the infrared sensor, flushing logic, and all mechanical components within this secure enclosure, the system is shielded from tampering, impact, and theft. This is the gold standard for high-security environments where fixture uptime is critical.
• Precision Piston Technology: Hydrotek’s proprietary industrial-grade piston design offers a significant performance advantage over traditional diaphragm valves. The piston mechanism ensures a highly accurate 0.125 GPF flush regardless of water pressure fluctuations and is exceptionally resistant to mineral deposits and debris—the primary causes of valve failure in high-traffic restrooms.
• Corrosion-Resistant Construction: Built with a high-quality brass valve body and industrial-grade VSI silicone elastomer seals, the system is engineered to withstand the aggressive effects of chlorine and chloramines found in modern municipal water supplies.
• Top Spud Integration: Configured for a 3/4" top spud connection and including a 3/4" inlet stop, this system remains concealed for security while interfacing seamlessly with standard top-access ultra-high-efficiency urinal fixtures.

Advanced Sensor & Logic Features

• Ultra-High-Efficiency Conservation: At just 0.125 GPF, this valve is a critical component for achieving the highest levels of water efficiency and meeting strict green building mandates without compromising on hygiene or performance.
• Touchless ADA Compliance: Provides a 100% hands-free experience, fulfilling all ADA accessibility requirements and significantly improving facility hygiene by eliminating common touchpoints and reducing cross-contamination.
• Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, the HB8-D1T-0125-WB is the ideal solution for retrofitting facilities where hardwiring is difficult or for new construction seeking simplified installation.
• True Mechanical Manual Override: Features a standard manual-mechanical override button that remains fully functional even in the event of battery exhaustion, ensuring the urinal is always operational.
• Automated Hygiene (Sentinel) Flush: Includes a built-in 24-hour sentinel flush feature that automatically activates the valve during periods of inactivity. This maintains the trap seal to prevent sewer gases from entering the restroom.
