Q&A: All About Check Valves
Question: What is the most reliable type of check valve?
Answer: The most reliable type of check valve is the swing check valve. Swing check valves are a type of mechanical valve that allows fluid to flow in one direction only. They have a hinged disc that swings open when the flow of fluid is in the correct direction, allowing it to pass through unimpeded. When the flow reverses, the disc swings closed, preventing backflow.Swing check valves are highly reliable because of their simple design and mechanism. They are self-operating, meaning they do not require any external power source to function. The swinging disc provides a tight seal against the valve seat, preventing any leakage or backflow. Additionally, swing check valves have low pressure drop, which means they do not restrict the flow of fluid when open.Overall, swing check valves are widely used in various industries for their reliability in preventing backflow and protecting equipment from damage. They are particularly suitable for applications where a tight seal is required and where backflow could be harmful.
