Introduction to Check Valve
A check valve, also known as a non - return valve or one - way valve, is a mechanical device that allows fluid (liquid or gas) to flow through it in only one direction. It is an essential component in many industrial and commercial systems, including water supply networks, oil and gas pipelines, chemical processing plants, and power generation facilities. The main function of a check valve is to prevent backflow, which can cause damage to equipment, contaminate the fluid, or disrupt the normal operation of the system.
