Axial Flow Check Valve

Overview

An axial check valve is the preferred solution for critical non-return applications such as the protection of rotating equipment and systems where low pressure loss, stable operation and dynamic behaviour are essential.

Key features

• Streamlined Flow Path: The valve body has a full-port, streamlined design that minimizes flow restriction and turbulence. This allows for an axial (inline) flow path, reducing pressure loss compared to other check valve designs.
• Disc Design: Utilizes a lightweight disc that travels in a straight line (axial direction) to open and close the flow path. The design minimizes inertia and allows for rapid opening and closing.
• Spring Mechanism: A spring holds the disc in position and helps regulate its movement. The spring tension can be adjusted in some designs to optimize performance for specific flow conditions.
• Silent Operation: The streamlined design and rapid disc movement minimize slamming and noise, making them suitable for quiet operation environments.

Benefits

• Low Pressure Loss: The streamlined flow path and full-port design minimize resistance to flow, leading to lower pressure drops within the piping system. This translates to improved efficiency and reduced energy consumption.
• Non-Slam Operation: The rapid disc movement and spring mechanism prevent slamming shut, minimizing noise and wear on the valve components. This is particularly beneficial in applications where water hammer (pressure surges) can be a concern.
• Fast Response: The lightweight disc and axial flow path enable rapid opening and closing, making them suitable for applications requiring fast response times.
• Durability: The simple design with minimal moving parts contributes to their durability and reliability.
• Easy Maintenance: The simple design often allows for easy maintenance and inspection procedures.
