Hydrotek H8D1B-0125-WB Ultra-High Efficiency Concealed Urinal Flush Valve

The Hydrotek H8D1B-0125-WB is an industry-leading, sensor-operated flush valve engineered for maximum water conservation in high-traffic commercial environments.This hardwired, AC-powered unit delivers a precision 0.125 GPF (1/8 Gallon per Flush), making it one of the most water-efficient solutions available for facilities aiming to achieve peak LEED certification or comply with the strictest green building codes.

Designed for concealed installation, the H8D1B-0125-WB features a durable wall box that houses the mechanical and electronic components, protecting them from vandalism and providing a sleek, professional finish for 3/4" back spud urinal fixtures.

Performance and Engineering Excellence

• Precision Piston Operation: Unlike standard diaphragm valves, this unit utilizes a slow-closing piston mechanism that ensures consistent performance and accurate flush volumes across a wide range of water pressures (10–125 PSI).
• High-Copper Brass Construction: The valve body is cast from high-copper, low-zinc brass to provide superior resistance against dezincification, ensuring long-term structural integrity in harsh water conditions.
• Chemical-Resistant Piston Seals: Equipped with proprietary VSI silicone elastomer seals that remain unaffected by high concentrations of chlorine, chloramines, and ammonia.
• Automated Hygiene Monitoring: A built-in 36-hour sentinel flush automatically clears the fixture during periods of inactivity to maintain the trap seal and prevent the migration of sewer gases.

Advanced Electronics and Power Reliability

• Hardwired Dependability: Powered by a 120V AC plug-in adapter (12V DC output), this unit provides constant power for high-frequency use without the maintenance requirements of battery replacements.
• Touchless ADA Compliance: The infrared sensor provides a sanitary, "no-hands" experience, significantly reducing the risk of cross-contamination in public restrooms.
• Integrated Diagnostics: The electronic system includes self-diagnostic logic and a manual reset function to simplify troubleshooting and facility maintenance.
• Dual-Action Flush: Includes a manual-mechanical override button, ensuring the urinal remains operational in the event of a power outage or electronic interruption.

Installation and Technical Specifications

• Concealed Design: Includes a 13" x 12" stainless steel wall box for a secure, flush-mount installation.
• Standard Connections: Features a 3/4" I.P.S. angle stop valve with a vandal-resistant cap and a 3/4" back spud coupling.
• Field Adaptability: Includes an adjustable tailpiece to accommodate various wall thicknesses and rough-in requirements.
• Debris Protection: A standard self-cleaning filtering system protects the solenoid and piston from sediment and waterborne particles.
