What is ANSI Swing Check Valve?

ANSI Swing Check Valve is a fluid device designed for one-way flow of liquid or gas. It has a disc that swings on a hinge, opens to allow fluid to flow in, and then closes to prevent backflow. Swing Check Valve designs come in a variety of sizes with different features to suit specific types of applications.

There are two main design standards for ANSI Swing Check Valve, one is API 594 Swing Check Valve, and the other is API 6D Swing Check Valve.
