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 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.
