Non-return valves. Buy online at the best price

A non-return valve , also known as a check valve or check valve, is a device used in piping and duct systems to allow a flow of fluid (liquid or gas) to flow in one direction and prevent it from flowing in the opposite direction. . These valves are designed to prevent fluid backflow and keep it in the desired direction.

Non-return valves operate by using an internal mechanism that allows fluid to flow freely in one direction (forward flow) and automatically closes when flow is detected in the opposite direction (reverse flow). This can be achieved through different mechanisms, such as a gate, disc, ball, flap, diaphragm or other devices that block the passage of fluid when the pressure or flow in the undesired direction exceeds a certain threshold.

Non-return valves are essential in a variety of applications, including plumbing systems, heating systems, cooling systems, pumping systems, compressed air systems and many other industrial and commercial applications. Its use ensures that fluids flow in the correct direction, avoiding equipment damage, safety issues, and unwanted system backups.

The pressure ranges are very wide depending on the application and the material it is made of, in steel, stainless steel, brass, plastic and its derivatives, nickel-plated brass. Non-return valves are applied in all types of industry.
