Top 10 Check Valve Suppliers in the world 2025

Introduction to Check Valve

A check valve, also known as a non - return valve, reflux valve, retention valve, foot 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 designed to prevent backflow, which could cause damage to equipment, contamination of systems, or inefficiencies in processes.

Check valves operate automatically, usually by means of a disc, ball, or piston that is moved by the pressure of the fluid flowing in the forward direction. When the pressure in the reverse direction exceeds a certain level, the valve closes to block the flow. They are widely used in various industries such as oil and gas, water treatment, power generation, chemical processing, and HVAC systems.
