Check Vavle

  • Grooved Swing Check Valve
    Grooved Swing Check Valve
    Brief:
    Grooved Swing Check Valve is used to prevent backflow of fluid in pipelines. Its valve disc swings by gravity and will only open when fluid flows in one direction. When fluid flows back, the valve disc will automatically close to ensure the normal operation of the system. The groove connection method simplifies the installation process and is commonly used in water pipelines and fire protection systems.
  • Swing Check Valve
    Flanged Swing Check Valve Flanged End
    Brief:
    The 300 PSI Flanged Swing Check Valve is designed to prevent reverse flow in fire protection, water supply, and industrial piping systems.
    With a swing-type disc and flanged end connections, this valve provides reliable one-way flow control, low pressure loss, and stable performance under high working pressure.

    Engineered in accordance with recognized international standards, it is suitable for both horizontal and vertical installations where dependable backflow prevention is required.
  • video Wafer Butterlly Check Valve
    Wafer Butterlly Check Valve
    Brief:
    The Wafer Type Dual Plate Check Valve is a compact non-return valve designed to prevent reverse flow in piping systems.
    It features two independent valve plates supported by torsion springs, allowing the plates to close rapidly and automatically when flow stops, effectively eliminating backflow and reducing water hammer.

    With its wafer-type design, the valve can be installed between flanges in both horizontal and vertical pipelines, offering space-saving installation and reliable performance across a wide range of applications.
  • video Cast Iron Flange Swing Check Valve Metal Seated for Water Oil & Steam
    Cast Iron Flange Swing Check Valve
    Brief:
    The cast iron flanged swing check valve is designed to prevent reverse flow in pipeline systems by automatically closing with the pressure of the fluid. Manufactured from high-quality cast iron with a durable metal-seated disc, this valve offers reliable sealing performance and extended service life, even under demanding operating conditions. Its flanged end connection ensures easy installation and secure integration with standard pipeline configurations.

    This swing check valve is widely used in water supply, oil transmission, and steam pipeline applications, providing stable flow control, corrosion resistance, and minimal maintenance requirements. The smooth internal flow passage reduces pressure loss, while the robust hinge mechanism guarantees consistent operation and dependable backflow prevention. Ideal for industrial facilities, mechanical systems, and general pipeline networks, this valve delivers long-term reliability and cost-effective performance.
  • video Rubber Coated Ball Check Valve (Spherical Check Valve)
    Rubber Coated Ball Check Valve (Spherical Check Valve)
    Brief:
    The Rubber Coated Ball Check Valve (Spherical Check Valve) is a non-slam, silent-type check valve designed to prevent backflow in water and wastewater pipeline systems.
    It utilizes a rubber-coated rolling ball as the valve disc, allowing smooth opening and closing under medium flow, ensuring excellent sealing performance and reduced hydraulic loss.

    With a full-bore flow channel design, this valve provides higher flow capacity and significantly lower head loss compared to conventional swing check valves, making it especially suitable for pump outlets and drainage systems.
  • video Silent Check Valve
    Silent Check Valve
    Brief:
    The Silent Check Valve is a spring-assisted, non-slam check valve designed for water supply and drainage systems.
    The valve disc is guided by a central shaft at both inlet and outlet sides, ensuring precise alignment, fast response, and stable operation.

    By combining a spring-loaded disc, streamlined flow path, and short closing stroke, this valve effectively eliminates water hammer, reduces noise, and delivers reliable sealing performance. It can be installed horizontally, vertically, or at any inclined angle, making it suitable for various pipeline layouts.

Check valves are used to prevent reverse flow in pipeline systems. They allow fluid to flow in one direction and automatically close when backflow occurs.
