Flap Valve Rectangular

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Unidirectional Flow Control: Designed to prevent backflow and regulate fluid flow in industrial systems, ensuring safe and efficient operation.
  • Lightweight FRP Construction: Combines corrosion resistance and durability with reduced weight for easy installation and handling.

Key features

  • 1. Corrosion-Resistant FRP Material

    • With corrosion-resistant fiberglass-reinforced plastic (FRP), ensure durability in harsh industrial environments—up to 30% lighter than traditional metal valves*. This material combination withstands chemical exposure and wear, extending service life in applications like sewage or chemical processing.

  • 2. Smooth Surface & Flanged Design

    • With a smooth surface finish and flanged design, achieve effortless installation and maintenance. The rectangular (square) pattern aligns seamlessly with standard ducts or pipes, reducing alignment challenges compared to irregularly shaped valves*.

  • 3. Lightweight Construction for Easy Handling

    • Up to 20% lighter than metal alternatives*, reduce installation effort and transportation costs. The FRP material’s low weight simplifies deployment in elevated or confined industrial spaces.

  • 4. Versatile Industrial Scenario Solutions

    • Designed for industrial applications, effectively manage fluid flow in water supply, sewage systems, and chemical processing. The rectangular shape optimizes space efficiency in rectangular channel setups, outperforming round-valve configurations in such contexts*.

  • 5. Compliance with European Certification Standards

    • Meets EPR France/Germany Packing and EN124 standards, ensuring regulatory compliance and safety in European markets. This certification guarantees eco-friendly disposal and structural reliability for public infrastructure projects.

Supplier's note

  1. Technical Breakthroughs:

    • FRP Material: 40% lighter than traditional metal valves, reducing installation costs.
    • Smooth Surface: 20% lower pressure drop than standard flap valves.
    • EU Certifications: Streamlined compliance for projects in France/Germany.

  2. Version Selection Guide:

    • Base Model: Ideal for standard industrial applications (e.g., water treatment).
    • Advanced Model: For high-pressure systems (e.g., chemical processing plants).
    • Pro Model: Suitable for extreme environments (e.g., oil refineries) requiring heat/pressure resistance.

With the Pro Model’s 15 bar rating, you can safely handle high-pressure fluids. Pair its 100°C tolerance with FRP’s corrosion resistance to ensure longevity in aggressive chemical environments. The Base Model’s EU certifications simplify deployment in regulated markets.

*Note: Pro Model weight reduction achieved through advanced FRP composite technology.
