Hydrotek H8CB-128-WB High-Efficiency Closet Flush Valve

The Hydrotek H8CB-128-WB is a heavy-duty, sensor-operated closet flush valve designed for high-traffic commercial environments that require a concealed, vandal-resistant installation. This AC-powered unit delivers a water-conserving 1.28 GPF flush, meeting stringent modern efficiency standards without compromising on waste evacuation. The inclusion of a dedicated wall box makes it an ideal solution for back-spud closet bowls, offering a clean, streamlined aesthetic while protecting the internal components from tampering.

Engineered for Longevity and Performance

• Superior Material Integrity: Constructed from high-copper, low-zinc brass casting, this valve is engineered for maximum dezincification resistance.
• Advanced Piston Mechanism: Features a slow-closing, piston-operated flushing system that ensures consistent performance across a wide pressure range of 10–125 PSI.
• Chemical-Resistant Seals: Equipped with VSI silicone elastomer piston seals that are unaffected by harsh treatment chemicals such as chlorine, chloramines, and ammonia.
• No-Hands Hygiene: The ADA-compliant infrared sensor provides "no-hands" operation to minimize the spread of bacteria in public restrooms.
• Sentinel Flush: Includes a 36-hour sentinel flush feature to maintain the trap seal and ensure fresh water remains in the fixture during periods of inactivity.

Smart Power and Diagnostics

• Hardwired Reliability: Powered by a standard 120V AC (60 Hz) plug-in adapter, providing constant power without the need for battery replacements.
• Internal Protection: A standard self-cleaning filtering system protects the internal solenoid and piston from waterborne debris, reducing long-term maintenance costs.
• Electronic Monitoring: The self-diagnostic electronic system allows for quick troubleshooting and includes a manual reset function.
• Secondary Operation: A standard manual-mechanical override button is included, ensuring the fixture remains functional even in the event of an electronic failure.
