Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Water Level Regulation: Designed to automatically control and maintain consistent water levels in plumbing systems through a hydraulic diaphragm and floating ball mechanism.
  • Multi-Material Construction: Combines durable brass components with corrosion-resistant plastic (PA66 nylon) for longevity and adaptability in medium-pressure water applications.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a brass body and nylon PA66 components, you can ensure long-lasting durability in water systems. Unlike plastic-only valves, this hybrid design resists corrosion and wear, extending lifespan by up to 30%*.

  • 2. Transparent Monitoring Design

    • With a see-through body, you can visually track the float mechanism in real-time, ensuring optimal water level control without manual checks. This feature reduces maintenance efforts compared to traditional opaque valves*.

  • 3. Hydraulic Efficiency for Medium Pressure

    • With hydraulic power optimized for medium-pressure systems, you can maintain stable water flow in toilets and cisterns. Outperforms standard valves in preventing leaks under fluctuating pressure conditions*.

  • 4. Versatile Scenario Solutions

    • Designed for both residential and commercial use, you can install it in home toilets or high-traffic plumbing systems. Its compact 30mm size ensures adaptability without compromising performance in small spaces*.

  • 5. Eco-Friendly Compliance

    • With EPR certifications from Germany and France, you can meet strict environmental regulations for packaging and disposal. This makes it a greener choice compared to non-certified alternatives*.

  • Notes:

    • Material Technology: Highlighted brass/nylon durability vs. plastic-only designs.
