American Standard Ultima Selectronic 1.28 GPF Flush Valve
This piston-type, battery-powered flush valve from American Standard is designed for 1-1/2 inch exposed spud bowls. It features a self-cleaning piston and an integral wiper spring that minimizes clogging and reduces maintenance. The proximity sensor allows customizable flush volume and timing, and the device includes a mechanical override for manual operation without power. Suitable for high-use restrooms seeking reliable, touchless performance with robust water control.
American Standard Ultima Selectronic 1.6 GPF Flush Valve
This 1.6 GPF unit emphasizes dependable performance even with poor water quality. It uses a self-cleaning piston with an integrated wiper spring and a programmable proximity sensor for easy adjustments. The valve is designed to fit flushometer bowls with a 1-1/2 inch exposed top spud, and its electronics reduce ghost flushing while offering a mechanical override for non-powered operation.
American Standard Ultima Selectronic 1.1 GPF PWRX Valve
Powered by a robust PWRX system, this 1.1 GPF valve uses advanced electronics to prevent ghost flushing and provides a mechanical override to flush without power. It is designed to maintain consistent flush volumes across different inlet pressures, ensuring reliable operation in variable water conditions. The self-cleaning piston and integrated wiper reduce maintenance needs over time.
TECHO Touchless Flush Kit
TECHO’s kit provides a fast upgrade path from manual to automatic flushing. It installs in roughly 10 minutes and features an adjustable sensor to control activation range and water volume. The IP67 rating indicates strong water resistance, making it suitable for humid or splash-prone restroom environments. This option emphasizes ease of retrofit and reliable hands-free operation.
Sloan Regal 111 SFSM Exposed Sensor Valve
The Sloan Regal 111 SFSM is a benchmark for commercial flushometers, offering infrared sensing and a true mechanical override. It supports a 1.6 GPF flush and uses ADA-compliant features to promote water conservation. The system is designed for high-traffic facilities where reliability and hygiene are critical priorities, combining sensor-based operation with robust mechanical control options.
EBV-129-A-C Water Closet Electronic Control Module
This electronic control module is compatible with Sloan Optima G2 and ECOS Sensor flushometers, including 1.28 and 1.6 GPF configurations. Its modular design supports quick installation and simple maintenance, offering a flexible solution for replacing or upgrading sensor components in commercial restrooms. The module aims to reduce water waste by triggering flushes only when sensing is appropriate.
EBV-129-A-U Urinal Control Module
Designed for Sloan Optima G2 and ECOS urinal sensors, this control module supports 0.5 and 1.0 GPF configurations. It facilitates automatic, touchless flushing with a high-sensitivity infrared sensor, aiming to improve restroom hygiene while conserving water. Replacement parts are intended for straightforward compatibility with Sloan’s sensor modules across multiple urinal models.
Buying Guide: Key Considerations For Electronic Toilet Flush Valves
- Flush volume and water efficiency: Look for adjustable GPF settings or models with precise pressure compensation to ensure consistent performance across various inlet pressures and occupancy levels.
- Sensor technology: Compare infrared vs. capacitive proximity sensors. Infrared sensors are common in high-traffic areas, while capacitive sensors may offer subtle activation control in smaller restrooms.
- Maintenance and reliability: Self-cleaning pistons and wiper springs reduce clogging and maintenance needs. Consider those with electronic ghost-flush prevention and robust override options.
- Compatibility and retrofit options: Check spud size (e.g., 1-1/2 inch exposed top spud) and compatibility with existing flushometer bowls or toilet models to minimize installation complexity.
- Power source and overrides: Battery-powered units are easier to install where wiring is impractical. Ensure there is an accessible mechanical override for manual operation during power interruptions.
- Durability and build materials: Look for corrosion-resistant alloys (dezincification-resistant brass) and IP-rated housings for water resistance and long service life.
- Installation and maintenance cost: Assess not just initial cost but also replacement parts availability, ease of installation, and expected maintenance intervals in your facility context.
- Hygiene and safety: Touchless operation reduces germ spread in high-traffic environments; choose sensors with reliable response times and low false-trigger rates.
In summary, the best electronic toilet flush valves balance precise water control, reliable hands-free operation, and straightforward maintenance. When selecting for a facility, weigh sensor reliability, water savings, retrofit flexibility, and long-term serviceability to achieve the lowest total cost of ownership.
