   What is a check valve?

   • A check valve, also known as a non-return valve or one-way valve, allows the fluid to flow in only one direction. It is designed to prevent backflow, the reverse flow of fluids in a pipeline, and ensure the unidirectional fluid flow in the piping system.

   What causes a check valve to close?

   • Higher pressure on the outlet causes the valve to close. A check valve, also known as a non-return or one-way valve, is a two-port safety device that allows gas, steam, or fluid to flow in a single direction. Its primary purpose is to restrict backflow in a system.

   How does a spring-loaded check valve work?

   • Spring-loaded valves that you can mount in any flow orientation helps to prevent reverse flow. This type of valve employs a spring to help close the check valve and doesn’t require backflow pressure or gravity to function. When any pressure changes in the pipe leading to flow reversal, the valves will protect equipment from damage due to backflow.

   What is a stop check valve?

   • Stop check valves can be deliberately closed using external mechanisms. They offer fluid flow control regardless of the forward or backflow level. These valves prevent damage to equipment, including pumps and boilers. One challenge of the swing check valve is that it closes abruptly due to gravity.

   How do in line check valves work?

   • In-line valves are also known as Nozzle Check Valves or Silent Check Valves. These valves employ a centrally guided stem-disc assembly along with a compression spring. To open the valve, the flow pressure must be more than the spring force and cracking pressure. In that case, the flow pushes the disc allowing the flow.

   What is a Check Valve? The valve that is used to prevent backflow in a piping system is known as a check valve. It is also known as a non-return valve or NRV. The pressure of the fluid passing through a pipeline opens the valve, while any reversal of flow will close the valve.

   Aug 28, 2020 · A Check valve is a mechanical device used in piping and pipeline systems to prevent back-flow. Check valves allow fluid flow only in the forward direction that’s why it is called a one-way valve or non-return valve. They work on the principle of differential pressure.

    Check valves, which are more generically known as non-return valves, are intended for control of fluid flow just like any other valve, but their contribution to the system is to keep fluid from returning in the direction that it came from. This principle is used widely in nature; the human body contains a number of check valves.
