What is Non-Return Valve
Non-return valves are designed to allow fluid to flow in one direction only. They typically have a flat side and a curved side, although some may have an hourglass shape. When liquid enters from the outside edge, it pushes against the flat face of the valve. Since the liquid has no escape, it passes through the valve and towards its destination. This creates suction within the chamber, which prevents any other fluid from entering it. This ensures that the liquid stays contained in the desired location and prevents backflow during operation.
Types of Non-Return Valve Market
Ball Non-Return Valve
A non-return ball valve is a device that can serve as a semi-open or closed thermal relief or backpressure relief valve. It is designed to reverse the flow direction when the temperature surpasses its predetermined threshold. This design feature also helps to control the water hammer in steam systems. It releases pressure from the scenario by allowing fluid to exit from the downstream side of the valve when it detects excessive upstream forces.
Non-Return Valve
Non-return valves, also known as check valves, are valves that permit fluid to flow in one direction only. They are usually shaped like hollow discs or cylinders with a flat side and a curved side, although they may also have an hourglass shape. Still, this is uncommon. Fluid entering from the outer edge pushes against the flat side of the disc. Since the fluid has no exit, it is forced through and outwards in the direction of its destination.
Swing Non-Return Valve
Swing non-return valves are intended to be opened by fluid pressure to enable flow and closed when there is no more backflow. They permit one-way fluids, gases, or liquids traffic within their installation location.
Diaphragm Non-Return Valve
Diaphragm non-return valves operate without closing springs or discs, making them ideal for use in applications where the media is dirty or corrosive. During regular operation or service conditions, they remain open.
Uses of Non-Return Valves
Pumps
Non-return valves are commonly installed in pumps to prevent backflow and maintain a smooth flow through the system.
Domestic Use
Non-return valves are commonly utilized in pipelines to prevent the backward flow of liquids and gases by applying back pressure on the fluid in one direction but not in the opposite direction.
Industrial use
Non-return valves are employed in industrial applications to prevent the reverse flow of fluids, gases, or steam. The valve effectively stops the return or reentry of a continuously flowing stream, making it beneficial in fire protection systems and for liquids such as oils, alcohol, and others.
These are the different types and uses of non-return valves. The vivid application has propelled the growth of the non-return valve market, leading to a rise in demand.
