As the name prospects, it replaces the disk with a ball to prevent reverse flow. The working is pretty straightforward; under pressure, the ball will lift off the pipe outlet and let the fluid move in one direction, but as the pressure drops, the ball will fall over the outlet and stops the flow.
Double door or Butterfly check valve features a disc divided into two doors from the center. Both are connected through a hinge that opens up to allow forward water flow and shuts to prevent backward flow. The valve is comparatively small and lightweight, perfect for low-pressure fluid and gas application.
Lift check valve is exceptional; it is the best one for high-pressure usage. In the lift valve, the pressure lifts up the piston or ball to allow the water flow, while as the water starts to flow in the reverse direction, there is no pressure to keep the ball or piston lifted; hence it fell and stops the flow. These valves are also leak-resistant.
Stop check valves are not dependent on gravity or pressure like many other valves. It allows override control regardless of flow direction. We can manually close the stop valve through an external mechanism to control or stop the flow.
The common use of swing check valves is where we have a high percentage of solids in fluid. The disc swings to allow the flow and swings back in its original position to restrict the flow of fluids. It opens and shut slowly and good for pipes where the on/off cycle count is lesser.
It uses a spring-powered disc to control the flow; it is available in wafer-type and lug-type disks, which tilts up and starts floating under pressure. As the flow reverts, the disc sink and returns to a close position.
We are using check valves in almost every industry because of their benefits and low cost. Below are some industries where check valves are a major component.
The mining industry is versatile and uses many valves and pumps for many different purposes like dewatering and watering. Check valves are used throughout the mines; many pipes take and bring the water from different locations. A critical application of the check valve is in the dewatering system. The system is responsible for extracting water from the extraction or mining site, and reverse flow will destroy the pumps and bring all the water back to the site. That’s why check valves are necessary.
Moreover, they are used in autoclaving, pump isolation, and discharge.
The main problem in the food and beverage industry is contamination by harmful products. Sanitary check valves stop pathogens and other elements from entering the product. Moreover, they are mounted in boiler feed and discharge, cookers, refrigerators, and steam lines to perform their primary task of preventing reverse flow and water hammers. They also guard against the falling pressure by preventing condensate backup when inlet steam is reduced.
The oil and gas industry are expensive and has a lot of maintenance costs, so it is better to get a valve with less maintenance cost and incredibly functioning for that check valve. The check valve has a considerably low maintenance cost than other valves, and it precisely performs the task of stopping reverse flow.
Moreover, it has a low-pressure drop which lowers the energy consumption, which also helps in chatter reduction in pipes.
The pharmaceutical industry is pretty much like food and beverage, but it requires extra protection against external elements. The industry also needs effectiveness and efficiency to fight against the reverse flow and water hammer. To overcome the problems of cleanness, water hammer and backflow check valves are used to tackle all three issues systematically.
Power plants are the most important thing for a country; they power the entire country and runs all the industries. They need special care against the reverse flow because a slight flaw can bring the whole system down. That’sThat’s why check valves are so crucial in power plants.
Check valves are a crucial part of every major industry; they play an essential role and save many things from any possible damage. So, it is absolutely essential to buy a high-quality check valve. Numerous manufacturers are selling sub-standard check valves.
So, here are manufacturers whose products are made from high-quality material, and their manufacturing plants are ISO standardized.

Check valve is a crucial part of an industry as it is controlling the major flow and prevents disaster due to water hammer. That’s why it is vital to get the right check valve for yourself.
Below are some crucial points that every check valve buyer must consider.
Firstly, we have the fluid, typically check valves are designed to handle freshwater and treated water, but they can handle some raw waste. The excess of sewage waste can cause complications. So, you should consider the type of fluid and the percentage of solid matter in the water. In this way, the valve will keep on functioning correctly for a long time.
Considering the flow characteristics of fluid is very important. There are rapidly closing and slowly closing valves. If the water pressure is fast, then the rapid closing of the valve will prevent slamming but causes a surge when the pump will start or shut down. The surge will have effects on the pump because a sudden change in pressure happens.
Check valves are also used in industries like oil and gas, pharmaceutical companies, food, beverages, and many others. So, a valve has to be able to qualify for all these products. Like in food and pharmaceutical industries, the valve most not cause contamination. Moreover, medicines have certain acids and salts, which can cause a reaction with the valve material hence causing contamination and substandard product. Likewise, in the oil industry, there is a risk of grease buildup so, the valve can work properly.
Lastly, the overall construction is critical because it has to bear strong fluid pressure.
Never forget to consider cost, ease, and speed of maintenance. This is important for the reliability and functioning of the valve. It also covers the type of check valve; for example, we cannot control the flow of fluid in the ball valve, and trying will cause jamming, clogging, and malfunctioning, which will destroy the valve, or you have to pay a lump sum amount to fix it. So, you must choose the right type of check valve for the right function and always consider the maintenance cost, speed and ease.
Non-Slam is the stage when the pump stops, and the flow is reversed. Some fluid may reverse back before the valve gets fully closed. Then the valve is closed, and a change in flow velocity creates kinetic energy, which is turned into the pressure of the fluid.
After closure, you might hear a slamming sound, it is not caused by the closing of the disk or ball, but the pressure spike creates this sound stretching throughout the pipe. We cannot reduce the slamming to zero because of the valve’s geometry; the closure is not fast enough to stop the reverse flow which causes slamming.
Although check valves are pretty solid and built to last for a long time but some factors can damage the check valve. Here are some common causes of damage in check valves.
Incorrect Installation is the leading cause of check valve damage. By installing it incorrectly, you will create problems in pipelines, pumps, and the valve itself because it might not be able to stop the reverse flow. So, it is better to keep a close eye on the valve and fluid’s flow, positioning, and orientation.
Many users neglect the significance of maintenance; it is a definite way to ensure a check valve’s long life and proper operation. One must have them check periodically and look for the signs of wear and tear and check the debris in the pipeline. Ignoring these signs can end up badly.
Reverse flow occurs due to improper functioning of the check valve. When the valve allows the reverse flow of water. It is dangerous for the pump because the reverse flow will spin the pump backwards, which will lead to severe pump damage.
Water hammer is a shock wave that happens when the fluid is forced to stop and change direction. It can cause damage to the pipeline, valve, fittings and joints.

When sourcing brass ball valves in the US, quality, reliability, and trust are often hard to balance — but not impossible.
The leading brass ball valve suppliers in the US include companies like NIBCO, Apollo Valves, Milwaukee Valve, and legend Valve, known for their domestic production, certification, and consistent quality.
Some ball valves are made overseas, others in America. How do you tell the difference? Let’s dig into what really matters.
Brass Ball Valve US
Finding ball valves made in the USA can be a challenge if you're not familiar with the manufacturers or their production lines.
Ball valves made in the USA include those from brands like NIBCO, Apollo Valves, and Milwaukee Valve, which manufacture many of their products in domestic facilities.
American-made valves usually stand out in terms of certification, material consistency, and traceability. But not all brands are fully domestic, and some only assemble locally using imported parts.
Here are some characteristics to help identify ball valves that are truly made in the USA:
Trait Description Certification UPC, NSF/ANSI, and Made in USA labels Material Consistency C or C low-lead brass standards Factory Origin Publicly listed plant locations in Indiana, South Carolina Compliance Meet Buy American Act and NSF 61-GOne thing I’ve learned from years of sourcing is that "Made in USA" sometimes means "Assembled in USA." So it's important to verify the origin of the raw materials and components. Most US-based buyers rely on brands like NIBCO, which has full control of its casting and machining processes within the US.
For buyers concerned about quality, this makes a huge difference — especially in government or commercial projects where submittals and traceability are a must.

Let’s look at these companies in more detail:
In my own sourcing experience, the brand choice often comes down to the balance between price, lead time, and certification. For municipal or government contracts, Milwaukee Valve and NIBCO win because of their traceability and certifications. For residential or light commercial use, Legend or Matco-Norca usually provide the best bang for the buck.
Also, don’t forget customer support — Apollo and NIBCO have invested in US-based teams that actually pick up the and understand technical terms. This matters when you're on a tight timeline or troubleshooting in the field.
There’s a lot of confusion online about where Apollo valves are actually made.
Yes, many Apollo valves are made in the USA, especially in their South Carolina facility, although some components may be sourced globally.
Apollo, or more formally Conbraco Industries, is headquartered in Matthews, North Carolina. They have a significant manufacturing presence in Pageland, South Carolina, where they produce many brass and bronze valves. What makes Apollo stand out is that they manage design, casting, machining, and assembly all under one roof for many of their key SKUs.
Here’s what I’ve seen through years of supplier audits and procurement:
Still, not all Apollo valves are made in the US. Some lower-cost product lines — like certain backflow preventers or mini valves — are imported or assembled using globally sourced parts.
One key advantage for North American buyers is their shorter lead time, especially compared to imports from China or India, where container delays and port congestion often cause trouble.
If you're a buyer like Jacky in Canada, managing seasonal inventory, Apollo’s stable production and shipping can reduce your risk of out-of-stock and delayed installations.
The biggest difficulty in manufacturing brass ball valves in the USA is the high cost of raw materials and labor, especially compared to countries like China or India.
Here’s a breakdown of the core challenges:
Brass is made primarily of copper and zinc. The price of copper is globally traded and often volatile. US manufacturers must buy high-grade, low-lead or lead-free brass (like C or C), which is more expensive than conventional brass.
Manufacturing ball valves involves skilled labor: CNC machining, assembly, testing, and quality control.
The EPA and local agencies strictly control emissions, lead content, and chemical handling.
Most American brass valve factories can’t match the mass production scale of mega-factories in Asia.
Many components — O-rings, Teflon seats, lever handles — are still sourced from overseas.
Several US-based brands still manufacture high-quality brass ball valves domestically — NIBCO, Apollo, and Milwaukee Valve are your safest bets.
