- When we think about that same pressure wave that closed the swing check valve, the spring in the spring check closes before the pressure wave gets there. Spring check valves are considered “ silent check valves ” by utilizing a spring to assist the poppet in closing the check valve prior to fluid flow reversal.

A spring check valve is designed to allow flow in one direction while preventing reverse flow. It features a single inlet and outlet and requires correct spring selection to function properly. Each spring check valve, like all check valves, has an arrow on its side indicating the direction of flow. Often referred to as non-return or one-way valves,...
Swing check valves allow flow in one direction and automatically close when the cracking pressure decreases. They are a form of butterfly valvewith a disc that covers the valve opening. The disc is attached to a hinge such that the disc can swing open or close when it is struck by the flow of the media. On the side of the valve body is an arrow tha...
For a spring-loaded check valve to function properly, it requires upstream pressure, known as cracking pressure, to remain open. The required cracking pressure depends on the valve type, construction, spring characteristics, and its orientation in the pipe. Cracking pressure specifications are typically measured in pounds per square inch gauge (PSI...
Swing check valves are among the most widely used and versatile types of check valves. While they share a similar function with spring check valves—preventing backflow—their operating mechanisms are distinct. All check valves, including swing types, serve the automatic function of halting reverse flow. Swing check valves are particularly suited for...
Check valves are designed to permit flow in only one direction and feature various stopping mechanisms in different shapes and designs. Their primary functions are to safeguard equipment, support efficient manufacturing processes, and prevent reverse flow.
A spring check valve is a check valve that ensures unidirectional flow and prevents reverse flow. They have a single inlet and outlet and must be placed in the proper orientation to function correc...Spring check valves have a spring that holds the closing disc until sufficient pressure is applied to force the spring to collapse and move the disc from the opening in the pipe.A swing check valve allows flow in one direction and automatically closes when the cracking pressure decreases. They are a form of butterfly valve with a disc that covers the valve opening.Swing check valves are activated by the flow of the media that pushes the hinged disc open by the force of the flow.Jul 9, 2020 · Installing a spring loaded check valve can prevent effects of water hammer; whereas a swing check valve can exacerbate the issue. Spring check valves are considered “ silent check valves ” by utilizing a spring to assist the poppet in closing the check valve prior to fluid flow reversal.
Sep 1, 2024 · A spring loaded check valve utilizes a spring to open/close. A swing loaded check valve opens/closes depending on fluid flow. Unlike the swing check valve, a spring check valve can reduce noise levels, water hammer effects and can also be used to control downward fluid flow.
A silent check valve is a type of check valve designed to prevent backflow in a pipeline. Unlike traditional check valves, the silent check valve is specifically engineered to minimize noise and pressure fluctuations, commonly known as water hammer, when the flow direction changes.
Jun 5, 2023 · Silent check valves have a spring-loaded disc that travels a short distance along the pipe axis to close automatically in a fraction of a second. They are also known as spring check valves or axial flow silent check valves. They are suitable for reducing noise and water hammer when swing check valves close quickly.
