General Infos about Check Valves

A check valve is a self-closing mechanism that allows fluids and gases to flow in one direction while preventing reverse flow. Fluids enter the valve at the inlet under pressure, forcing the disc off the valve’s seat and exiting through the outlet. The flow continues to be steady as long as the pressure required to keep the disc open is maintained. When the pressure drops, the disc returns to its original position, shutting off the flow.

Cracking pressure, which can range from 3 psi to 350 psi depending on the size, purpose, and function of the check valve, is the pressure that opens the valve. Check valves guarantee that gases or liquids are flowing in the correct direction and that tight seals are formed to prevent leakage. Check valves safeguard pumps and compressors from serious harm by limiting the flow of liquids.

 

Check valves have many names depending on their use and how they are made. Clack, non-return (NRV), reflux, retention, and one-way valves are only a few of their many names. Regardless of how simple their design and function are, they are critical in the protection of pumps, piping systems, and fluid flow.

 

The swing valve is the most common type of check valve, as shown in the illustration below. The disc is totally out of the way during fluid flow because it is a full port design. The disc is opened by the directional flow. The disc remains open as the flow continues. The disc moves into the closed position as the flow slows or ceases, due to gravity.

 

A check valve’s principal purpose is to prevent reverse flow, which can harm pumps and other devices. When a check valve closes, the fluid in a system slams against the closed check valve, causing a water hammer. This element of check valve operation necessitates its resilience and durability, as well as the use of high-quality materials.

 

Check valves can be noisy, thus they need to be quieted down. To that purpose, a variety of controls have been included. Springs, levers, or weights are built into the valve’s structure to control surges and prevent the valve from slamming shut. Check valves come in a plethora of shapes and sizes to suit a wide range of applications. There are both industrial and commercial applications for it. They regulate the flow of fertilisers and water in irrigation systems in gardens. Check valves are used in the aerospace and aircraft sectors to manage corrosive fluids, hydraulic systems, and fuel flow.

 

Recap: 

A check valve is a mechanical device that allows fluids and gases to flow in just one direction. Fluids enter the valve at the inlet under pressure, forcing the disc off the valve’s seat and exiting through the outlet. The flow continues as long as the pressure is maintained, but if the pressure drops, the disc returns to its seat and the flow is stopped off.

Check valves are critical for the safety of pumps, piping systems, and fluid flow. When a check valve closes, the fluid in a system slams against the closed check valve, causing a water hammer. Check valves come in a plethora of shapes and sizes to suit a wide range of applications. They’re used to control corrosive fluids, hydraulic systems, and fuel flow in the aerospace and aircraft sectors.
