Which statement correctly describes the nature of flow in a right angle check valve?

Unidirectional flow is a defining characteristic of a right angle check valve. This type of valve is designed to allow fluid to flow in only one direction, preventing backflow and helping to maintain the integrity of the system it is installed in. The mechanism typically involves a disc or a ball that moves to open when fluid flows in the intended direction and seals against the valve seat to prevent reverse flow.

The design and function of a right angle check valve ensure that it operates effectively in various applications, contributing to safety and efficiency in fluid systems. Understanding this unidirectional nature is essential for millwrights, as it influences how these valves are installed and used in conjunction with other system components.
