Question 1

What is a check valve?

Accepted Answer

A check valve is a mechanical device designed to allow fluid to flow in one direction only, preventing backflow and protecting the system from damage. It automatically opens and closes based on the direction of the flow.

Question 2

How does a check valve work?

Accepted Answer

A check valve operates using a valve disc or ball that moves to open or close the valve. When fluid flows in the desired direction, the disc or ball is pushed away from the seat, allowing flow through the valve. When the flow reverses, the disc or ball moves back to the seat, closing the valve and preventing backflow.

Question 3

Can check valves be installed in any orientation?

Accepted Answer

Many check valves can be installed in various orientations, but it’s important to follow the manufacturer's guidelines. Some check valves have specific installation requirements to ensure proper operation.
