Precision Engineering & Durability

• Heavy-Duty Brass Construction: Cast from high-copper, low-zinc brass to provide maximum resistance to dezincification, ensuring the valve maintains its structural integrity and finish in demanding high-traffic environments.
• Advanced Piston Mechanism: Features a superior, slow-closing piston flushing mechanism that ensures consistent cycle times and accurate flush volumes, regardless of fluctuations in water pressure.
• Industrial-Grade Seals: Equipped with VSI silicone elastomer piston seals, specifically formulated to resist the corrosive effects of chlorine, chloramines, and ammonia commonly found in municipal water supplies.
• Debris Protection System: Includes a standard self-cleaning filtering system that protects the internal solenoid and piston from waterborne sediment and mineral buildup, extending maintenance intervals.

Advanced Operational Intelligence

• Battery-Powered Independence: Operates on four (4) standard AA alkaline batteries, making it an excellent choice for retrofits or high-end installations where hardwiring is not preferred. Includes an integrated low-battery indicator.
• Touchless ADA Compliance: The advanced infrared sensor offers a sanitary, "no-hands" experience, ensuring full compliance with ADA accessibility requirements while minimizing cross-contamination.
• Smart Self-Diagnostics: Features an integrated electronic system with self-diagnostics and a manual reset function to simplify troubleshooting and facility management.
• Automated Hygiene (Sentinel Flush): Includes a built-in 36-hour sentinel flush feature to automatically activate the valve during periods of inactivity to maintain the trap seal and prevent sewer odors.
• True Mechanical Override: Equipped with a standard manual-mechanical override button, ensuring the urinal remains fully functional even in the event of battery failure.

Technical Specifications & Installation

• Fixture Compatibility: Designed for exposed installation on 3/4" top spud urinal fixtures.
• Standard Connections: Includes a 3/4" I.P.S. angle stop valve with a vandal-resistant cap and a 3/4" top spud coupling.
