A disc check valve, also known as a swing check valve, is a type of check valve used to control the flow of fluids (liquids or gases) in a piping system. Check valves are designed to allow flow in one direction while preventing reverse flow, thereby ensuring fluid flow in the desired direction.

Disc Valve
Disc check valves are widely used for their effective and economical solution for preventing backflow in piping systems, offering reliable performance and versatility in various industrial and commercial applications.
Key Features:
- Construction: A disc check valve typically consists of a valve body, a hinged disc, and a seat. The valve body contains the inlet and outlet ports, while the hinged disc swings open or closed to allow or prevent flow. The disc is typically made of metal, plastic, or another material that provides a tight seal against the seat when closed.
- Operation: The disc check valve operates based on the principle of fluid pressure. When fluid flows in the desired direction, it pushes against the disc, causing it to swing open and allow flow through the valve. When flow stops or reverses direction, the disc swings back into the closed position under its own weight or with the assistance of a spring, sealing against the seat and preventing backflow.
- Flow Characteristics: Disc check valves offer low resistance to flow in the open position, minimizing pressure drop and energy loss in the system. However, they may produce some turbulence or pressure fluctuations during operation due to the swinging motion of the disc.
- Bubble-Tight Shut-off:When fully closed, Audco Butterfly Valves provide bubble-tight shut-off, ensuring leak-free performance and maintaining system integrity and safety.
Application:
- Water Supply Systems: Used in municipal water lines to prevent contamination from reverse flow.
- Wastewater Treatment: Common in sewage treatment plants to ensure proper flow direction and protect against backflow.
- Industrial Processes: Employed in chemical processing and manufacturing to maintain fluid flow integrity and prevent contamination.
- Oil and Gas Industry: Used in pipelines and storage tanks to prevent reverse flow, enhancing safety and efficiency.
- HVAC Systems: Applied in heating and cooling systems to ensure fluid flows in the correct direction, protecting equipment.
Benefits :
- Effective Backflow Prevention : Disc check valves provide reliable prevention of backflow, safeguarding downstream equipment and processes.
- Compact Design : Their design is generally more compact and lightweight than other types of check valves, facilitating easier installation in tight spaces.
- Low Pressure Drop : Offers minimal resistance to fluid flow, ensuring efficient operation and lower energy costs.
- Rapid Response : The disc mechanism allows for quick closure, reducing the risk of water hammer and system shock.
- Durability : Constructed from robust materials (like stainless steel, PVC, or cast iron), they are resistant to wear and can handle various fluid conditions.
- Versatility : Suitable for a wide range of applications, including different fluids and pressures, making them adaptable across industries.
