A Disc Check Valve is a type of non-return valve that allows fluid (liquid or gas) to flow in one direction only, preventing backflow. It uses a flat or slightly curved disc as the closing mechanism, which swings or lifts off its seat when fluid flows forward, and closes tightly to block reverse flow.

Key Features:

• Disc Mechanism: The valve contains a disc mounted on a hinge or a pivot that moves to open or close based on flow direction.

• One-way Flow: Opens automatically when fluid flows in the forward direction, and closes by gravity, spring, or reverse flow pressure.

• Simple Design: Relatively simple construction, easy to maintain and reliable in operation.

• Material: Can be made from various metals (like stainless steel, cast iron, brass) or plastics, depending on the fluid and application.

• Installation: Typically installed in pipelines to protect pumps, compressors, and other equipment from damage caused by backflow.

Applications:

• Water supply systems

• Pump discharge lines

• HVAC systems

• Chemical and petrochemical industries

• Fire protection systems

• Oil and gas pipelines

Advantages:

• Prevents reverse flow and potential damage to equipment

• Low pressure drop when fully open

• Simple and cost-effective solution for backflow prevention

• Available in various sizes and pressure ratings to suit different systems
