What is a anti-flow back valve?

An anti-flow back valve, also known as a check valve, is a mechanical device that allows fluid to flow in one direction while preventing backflow. It operates based on pressure differentials, automatically closing when fluid attempts to reverse direction. This type of valve is commonly used in Plumbing, pumps, and various industrial applications to ensure system efficiency and prevent contamination. Its design helps maintain the integrity of fluid systems by avoiding reverse flow that could cause damage or inefficiencies.
