What is a Swing Check Valve?

A swing check valve is a type of check valve that allows flow in one direction and prevents flow in the opposite direction. It is called a "swing" check valve because of the swinging motion of the disc or flap inside the valve.

Here are the key features of a swing type check valve:

• Design:
  The valve consists of a disc or flap that swings on a hinge or a trunnion inside the body of the valve. The disc is free to move away from the seat when the flow is in the desired direction.
  
  
• Operation:
  When the flow of fluid is in the correct direction, the disc swings open, allowing the fluid to pass through. When there is a reverse flow or backflow, the disc swings back and rests against the seat, preventing the fluid from flowing backward.
  
  
• Hinge or Trunnion:
  The disc is typically mounted on a hinge or a trunnion (a pin or shaft) that allows it to pivot. The type of connection can vary depending on the design of the valve.
  
  
• Sealing:
  The disc is designed to provide a good seal against the seat when in the closed position, preventing any backflow.
  
  
• Installation:
  Swing check valves are generally installed in horizontal pipelines. Proper installation is crucial to ensure the disc swings freely and operates effectively.
  
  
• Size Range:
  Available in various sizes to accommodate different flow rates and pipeline dimensions.

Applications:
Swing check valves find applications in various industries where preventing backflow and ensuring fluid control are essential. Some common applications include:

• Water and Wastewater Systems
• Petrochemical and Chemical Industries
• Oil and Gas Processing
• Power Generation
• HVAC Systems
• Marine Applications
• Mining Industry
• Food and Beverage Processing
• Fire Protection Systems
• General Industrial Applications

Swing check valves are commonly used in applications where a tight shut-off is not critical, and the prevention of backflow is the primary concern. They are found in water and wastewater systems, industrial processes, and various other fluid handling applications. It's important to consider factors like pressure, temperature, and compatibility with the fluid when selecting a swing check valve for a specific application.
