Hydrotek HB8-R05D Automatic Flush Valve Retrofit Kit (0.5 GPF Urinal)

The Hydrotek HB8-R05D is a professional-grade, sensor-activated retrofit kit specifically designed to modernize manual Delany urinal flush valves. By upgrading to this high-efficiency 0.5 GPF (1.9 LPF) system, facility managers can achieve a 50% reduction in water consumption compared to standard 1.0 GPF valves. This battery-operated solution allows for a seamless transition to touchless operation, improving restroom hygiene and ensuring ADA compliance without the labor-intensive requirement of a full valve replacement.

Professional-Grade Engineering & Seamless Integration

• Specialized Delany Compatibility: The "D" designation confirms this kit is precision-engineered for a perfect mechanical fit with Delany manual urinal flush valves. It utilizes the existing heavy-duty brass valve body, allowing for a rapid "top-down" installation that minimizes fixture downtime.
• Touchless ADA Compliance: Replacing manual handles with an advanced infrared sensor provides a 100% hands-free experience. This not only meets ADA accessibility standards but also significantly reduces the transmission of germs by eliminating a primary touchpoint in the restroom.
• Industrial Piston Reliability: Hydrotek’s proprietary piston technology provides a distinct advantage over traditional diaphragm kits. The piston mechanism is highly resistant to mineral deposits and waterborne debris, ensuring a consistent 0.5 GPF flush volume even in buildings with older plumbing or fluctuating water pressure.
• Corrosion-Resistant Construction: Featuring a high-quality brass sensor housing with a durable chrome finish and industrial-grade VSI silicone elastomer seals, the HB8-R05D is built to withstand the rigors of high-traffic commercial environments and harsh municipal water conditions.

Advanced Sensor & Battery Features

• High-Efficiency Conservation: At 0.5 GPF, this kit is an essential component for facilities aiming to reduce utility overhead or meet specific green building certifications.
• Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, the HB8-R05D requires no electrical hardwiring. This simplifies the upgrade process in existing restrooms where running new electrical lines would be cost-prohibitive.
• True Mechanical Manual Override: Unlike many sensor valves that fail during power loss, this kit includes a standard manual-mechanical override button. This ensures the urinal remains fully operational for users at all times, preventing "out-of-order" scenarios during battery maintenance.
• Automated Hygiene (Sentinel) Flush: To maintain facility freshness, the integrated electronics include a 24-hour sentinel flush. If the fixture is not used for a full day, the system automatically triggers a flush to maintain the trap seal and prevent sewer gases from entering the building.
• Smart Self-Diagnostics: The system includes sophisticated self-diagnostic logic and a manual reset function, allowing maintenance staff to quickly troubleshoot performance and ensure maximum uptime.
