Hydrotek HB8RFKC-UD Automatic Flush Valve Retrofit Kit (1.0 GPF Urinal)

The Hydrotek HB8RFKC-UD is a precision-engineered, sensor-activated retrofit kit specifically designed to transform manual Delany urinal flush valves into high-performance, touchless systems. This industrial-grade solution allows facility managers to modernize their existing plumbing infrastructure to meet current hygiene and ADA accessibility standards without the significant expense of a complete valve replacement. Providing a consistent 1.0 GPF (3.8 LPF) flush, this battery-operated kit is the ideal choice for high-traffic commercial environments looking to reduce maintenance cycles and eliminate common touchpoints.

Professional-Grade Engineering & Seamless Integration

• Specialized Delany Compatibility: The "UD" designation confirms that this retrofit kit is custom-tailored for seamless integration with Delany brand manual urinal flush valves. The kit maintains the structural integrity of the existing brass valve body while introducing advanced electronic control and sensor technology.
• Touchless ADA Compliance: By replacing the traditional manual handle with a sophisticated infrared sensor, this kit provides a 100% hands-free user experience. This fulfills ADA requirements and significantly improves restroom sanitation by reducing the risk of cross-contamination.
• Precision Piston Reliability: Hydrotek’s proprietary piston design offers a distinct advantage over traditional diaphragm systems. The piston mechanism is exceptionally resistant to mineral deposits and debris, ensuring a precise 1.0 GPF flush volume even in buildings with older piping 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 HB8RFKC-UD is engineered to withstand the rigorous demands of municipal water treatment and heavy public use.

Advanced Sensor & Battery Features

• Battery-Powered Independence: Powered by four (4) standard AA alkaline batteries, this kit requires no electrical hardwiring. This simplifies the upgrade process for older facilities where running power to individual stalls would be cost-prohibitive.
• True Mechanical Manual Override: Unlike many electronic valves that become inoperable during power loss, the HB8RFKC-UD includes a standard manual-mechanical override button. This ensures the urinal remains fully operational for users at all times, even during battery maintenance cycles.
• Automated Hygiene (Sentinel) Flush: The integrated electronics feature a built-in 24-hour sentinel flush. If the fixture is not used for a full day, the system automatically activates a flush to maintain the trap seal, preventing sewer gases from entering the facility and keeping the fixture fresh.
• Smart Self-Diagnostics: The system includes sophisticated self-diagnostic logic and a manual reset function, allowing maintenance staff to quickly troubleshoot performance and minimize restroom downtime.
