Check valves are essential components in many piping systems, preventing the reversal of flow and ensuring smooth operations. However, traditional check valves can cause significant problems such as water hammer and valve slamming during operation. That’s where non slam check valves come into play! These innovative solutions provide a safer and more efficient alternative to traditional check valves, enabling seamless operations without any undesirable effects. In this article, we’ll delve deeper into the benefits of non-slam check valves and how they work to improve your system’s performance. So buckle up and let’s explore!

What are check valves?

Check valves are essential components of piping systems used to prevent the backflow of fluids. These valves allow fluids or gases to flow in only one direction, ensuring that they do not reverse and damage your system or cause any other unwanted effects.

Check valves come in different shapes and sizes, but most work on the same principle – using a movable disc or ball that opens when fluid flows in the right direction and closes when it tries to flow back. This simple mechanism ensures that your system operates smoothly without interruption.

However, traditional check valves can sometimes create significant problems such as water hammering or valve slamming during operation. Water hammer is a common issue caused by sudden changes in fluid velocity, while valve slamming occurs due to the impact of rapidly moving fluids against traditional check valve discs.

To solve these issues, non-slam check valves were introduced as safer and more efficient alternatives. These innovative solutions protect your piping systems from damage while allowing for smooth operations.

How do non slam check valves work?

When it comes to preventing reverse flow in pipes, check valves play a critical role. Non slam check valves, in particular, are designed to provide reliable performance and prevent water hammer during operation.

Non slam check valves operate based on the differential pressure between the inlet and outlet of the valve. When there is no fluid flow through the valve, it remains closed due to gravity and spring tension. As soon as forward flow begins, the force of the fluid overcomes gravity and opens up the valve.

As compared to traditional swing type or lift check valves that can produce slamming noise when closing due to sudden stoppage of backflow causing hydraulic shock waves within pipelines leading towards damage over time; non-slamming design doesn’t allow any such phenomenon. The disc in a non-slam check valve closes gradually with reduced velocity just before fully shutting off avoiding water hammer effect.

This slow-closing feature is what sets non slam check valves apart from other types of check valves. It ensures that there is no sudden closure upon shutoff which ultimately help extend service life reducing operational costs while improving safety for equipment and personnel alike.

Non slam check valves offer superior performance by providing quiet operation along with zero leakages ensuring smooth long-lasting system functioning even under high-pressure drop conditions without requiring frequent maintenance making them an ideal choice for any commercial or industrial application where safety matters most!

The benefits of non slam check valves

Non slam check valves bring a host of benefits to any piping system. First and foremost, they prevent the water hammer effect that is often associated with traditional check valves. The water hammer effect can be incredibly damaging to pipes, causing them to vibrate and even burst over time.

By eliminating this problem through their unique design, non slam check valves help extend the lifespan of piping systems while reducing maintenance costs. Additionally, these types of valves offer improved energy efficiency by minimizing pressure drops and increasing flow rates.

Non slam check valves are also highly reliable due to their durable construction materials such as stainless steel or ductile iron. Their simple yet effective design means there are fewer moving parts at risk for wear and tear or malfunction.

Non slam check valves provide greater flexibility in terms of installation orientation than traditional swing check valves thanks to their symmetrical body shape. This allows for easier integration into existing pipeline layouts without sacrificing performance or reliability.

How to select a non slam check valve

When selecting a non-slam check valve, there are several factors to consider. First, you should determine the required size and flow rate for your application. The valve’s size should match the diameter of your pipeline to ensure efficient operation.

Next, consider the pressure rating of the valve. This is especially important if your system experiences high pressure fluctuations or surges. A non-slam check valve with a higher pressure rating can withstand these sudden changes without causing damage to the pipeline or other equipment.

It’s also important to choose a reputable manufacturer who uses high-quality materials in their valves. Look for manufacturers who have a proven track record of producing reliable and durable valves that can withstand harsh operating conditions over an extended period.

Take into account any specific requirements that may be unique to your application. For example, some industries require special coatings on their valves to prevent corrosion or contamination.

By considering all of these factors when selecting a non-slam check valve, you can ensure that you get the right valve for your needs and avoid costly downtime caused by equipment failure or inadequate performance.


To conclude, non slam check valves are an essential component in many piping systems. They offer a variety of benefits such as preventing water hammering and reducing maintenance costs.

When selecting a non slam check valve, it’s important to consider factors such as the type of fluid being transported, the pressure rating required, and the temperature range that the valve will be exposed to.

By choosing the right non slam check valve for your application, you can ensure reliable performance and long service life. Whether you’re working with oil & gas or any other industry that requires efficient flow control solutions, investing in high-quality non-slam check valves is always a wise decision.
