Hydrotek H8D1B-05-WB Concealed Urinal Flush Valve

The Hydrotek H8D1B-05-WB is a heavy-duty, sensor-operated flush valve specifically engineered for concealed installations in high-traffic commercial environments. This AC-powered unit delivers a precision 0.5 GPF flush, providing significant water savings and helping facilities meet stringent LEED and local green building requirements. Furnished with a dedicated wall box and designed for 3/4" back-spud urinals, it offers a clean, streamlined aesthetic while protecting vital electronic and mechanical components from tampering or vandalism.

Engineered for Performance and Durability

• Precision Piston Technology: Features a superior, slow-closing piston flushing mechanism that ensures consistent performance across a wide pressure range of 10–125 PSI.
• Superior Material Composition: Constructed from high-copper, low-zinc brass casting to provide maximum resistance against dezincification and long-term structural fatigue.
• Chemical-Resistant Integrity: Equipped with VSI silicone elastomer piston seals that are specifically formulated to remain unaffected by chlorine, chloramines, and ammonia.
• Automated Hygiene Maintenance: Includes a 36-hour sentinel flush feature that automatically clears the fixture to maintain the trap seal and prevent the migration of sewer gases during periods of inactivity.

Advanced Electronics and Power Management

• Hardwired Reliability: Powered by a standard 120V AC (60 Hz) plug-in adapter (12V DC output), ensuring the valve is always ready for use without the maintenance cycle of battery replacements.
• Self-Diagnostic Intelligence: The integrated electronic system features self-diagnostics and a manual reset function to simplify facility troubleshooting and maintenance.
• No-Hands Operation: An ADA-compliant infrared sensor provides "no-hands" operation, promoting a more sanitary restroom environment by reducing cross-contamination points.
• Dual-Action Flush: Includes a standard manual-mechanical override button, ensuring the urinal remains fully functional even during power interruptions.

Installation and Technical Specifications

• Concealed Configuration: Designed for use with wall-hung back-spud urinal fixtures.
• Hardware Connections: Standard 3/4" I.P.S. angle stop valve with a vandal-resistant cap and 3/4" spud coupling for the back spud connection.
• Vandal-Resistant Enclosure: Includes a durable wall box and cover tube for a professional, tamper-proof concealed finish.
• Internal Protection: Features a built-in self-cleaning filtering system to protect the internal solenoid and piston from waterborne debris and sediment.
