What is the primary purpose of a check valve in a storage manifold?

• A. Prevent agent loss and safeguard personnel.
• B. Increase flow
• C. Increase pressure
• D. Redirect flow to a drain

Answer: (A)

Backflow prevention is the primary function of a check valve in a storage manifold. A check valve allows flow in only one direction and automatically seals if there is any reverse pressure or backflow. In a storage manifold, this prevents the agent from flowing back into supply lines or escaping to the environment, which protects both the material from loss and the personnel from exposure. It does not actively increase flow or pressure, and it isn’t meant to redirect flow to a drain; those tasks are handled by other components.
