Non-Return Valves

What is a Non-Return Valve (NRV)?

A non-return valve (NRV) is a type of industrial valve that is designed to prevent backflow and maintain or prevent a constant flow in one direction. It is also known as a check valve and is used in pipelines, appliances, and other types of plumbing or piping systems.

NRVs are typically manually or automatically operated. The valve is either opened or closed depending on the desired flow of liquid or gas. NRVs come in many different sizes and materials depending on their application, and a wide range of configurations are available to suit any type of piping system.

How Does a Non-Return Valve Work?

NRVs rely on their flow pattern to accomplish their function. When pressure is applied to the inlet side of the valve, it will open and allow the flow of liquid or gas to pass through. This can either be manually done or by way of a spring-actuated mechanism.

When the pressure on the outlet side of the valve gets to a certain point, the valve closes and prevents any additional flow from going in the wrong direction. This helps maintain a one way or constant flow of liquid or gas.

Advantages of a Non-Return Valve

There are numerous advantages to using non-return valves in a variety of different industries. One of the most significant advantages is that they allow for the maintainance of a certain pressure in piping systems, thus preventing backflow and reducing the risk of damage to the system.

NRVs are also relatively inexpensive and easy to install, making them ideal for simple plumbing systems or for use in system upgrades. Additionally, since most NRVs do not require power to operate, they can be used in off-grid applications or in remote locations if needed.

Finally, NRVs can provide a level of safety that is hard to achieve with other types of valves. By preventing backflow, they can prevent potential disasters caused by materials flowing in the wrong direction.

Types of Non-Return Valves

The two most commonly used designs of non-return valves are wafer check valves and swing check valves. Wafer check valves are much smaller than swing check valves and are typically used in more confined spaces. They are also less expensive and easier to install.

Swing check valves are generally much larger than wafer check valves and can handle much higher pressures. They are typically used in larger and more complex applications.

Conclusion

Non-return valves (NRVs) are an essential piece of equipment in many different industries around the world. They offer a strong level of safety and can be cost and space efficient solutions for applications where one-way flow of liquids or gases is desired.

NRVs are available in a variety of sizes and types to suit any application requirements. The two main types of NRVs are wafer check valves and swing check valves, each of which presents a different type of cost, size, and performance considerations.

Non-return valves are invaluable components that help keep our plumbing and piping systems safe and efficient. So the next time you need to install a valve, consider using an NRV and enjoy the peace of mind knowing that you have a reliable and secure system.
