Valve Casting Types | Materials | Manufacturer & Supplier

Valve Castings

The valve is used to change the passage section and the flow direction of the medium. It has the functions of diversion, cutoff, regulation, throttling, check, split or overflow relief. Valve castings are control components in pipeline fluid delivery systems. They come in a wide variety of sizes and sizes.

LEFLOW contains other products and information you need, so please check it out.

Valve castings are widely used in chemical, petrochemical, petroleum, paper, mining, electric power, liquefied petroleum gas, food, pharmaceutical, water supply, and drainage, municipal, mechanical equipment, electronics industry, urban construction, and other fields.

Our foundry is a reliable valve parts manufacturer and supplier for valve clients all over the world. We can make all kinds of casting valve components for a check valve, butterfly valve, ball valve, gate valve, control valve, globe valve, plug valve, etc.

The main types of valve castings

Gate Valve Casting

We can offer the scale of Gate Valve Castings from our foundry. Steel gate valve castings can be used for steam, water, air, oil, gas, and non-acid fluids. These valve castings are specially designed to endure high temperatures and load. As per the client’s requirements, we can customize different gate valve castings.

Globe Valve Casting

Globe Valve Casting is widely used in the Pharmaceutical, Chemical, and petrochemicals industries. This industry has a high demand for Globe Valve Casting. As one of the best valve casting manufacturers, our product has Long-lasting and stable properties. It is welcome by our customers because of its comfort of fitting, supreme tensile energy, and accurate engineering.

Ball Valves Casting

Ball Valves Casting is the most exported one in our foundry. It is accepted by our customers at reasonable prices, trusted quality. These castings are broadly used in railway industries for air dryer systems with their hardy frame, greater services, and conventional dimensions

Valve Investment Casting Process

As per the material specification and dimensions of valve casting parts, we can make them in different casting processes:

Process 1:

Sand Casting: Also a casting process for valve casting parts. Sand casting is suitable for both steel and iron valve castings. Compare with lost foam and lost wax castings, it is more suitable to make larger valve components. Normally, we will need to leave more machining allowance for further machining operation. The max weight we can cast is around 2 tons per piece.

Process 2:

Lost Wax Casting: Can make cast steel valve components, like carbon steel, stainless steel, and other cast steel alloys. Lost wax casting is a precision casting method for valve components. So we can achieve good dimensions and tolerances, smoother surface. Stainless steel valve casting parts are widely used in the silica sol casting process, which is another lost wax method. We can use this casting process for butterfly valves, ball valves, etc.

Process 3:

Lost Foam Casting: This casting method is more suitable for making precision cast iron valve parts. It can also get a good surface finish and size. Such as net shape or near-net shape valve castings will need no machining or just little machining allowance.

Most importantly, valve casting provides an easier and less time-consuming way to make replacement parts when a system’s current valves break down and deteriorate. We believe that Your drawing + our technology = Satisfactory product

Materials of Valve Casting Parts are as following:

The common materials and standards are as below:

Capabilities to supply valve castings

To supply finished valve casting parts, we have machining equipment as well (NC lathe, CNC, boring machine, drilling machine, etc) for different machining requirements. Besides, we also have the hydraulic testing capability to ensure workable valve castings. For large dimensions valve casting parts, to avoid casting defects, it is necessary to do magnetic particle testing and ultrasonic testing after casting.

In conclusion, you can enjoy lots of benefits to buy valve casting parts from our foundry. Like wide material selection, many casting methods, machining service, and so on. Once cooperating with us, you will feel lucky to cooperate with such a good supplier for our high quality and competitive prices. Even if you would like to source forged valve components, do not worry, we can also provide you with forged valve parts from another forging company. Just please contact us once you have the demands of valve components.

What factors should users consider when choosing to use butterfly valves as fluid controls? The following VALTECCN butterfly valve suppliers will explain the main factors to you for your reference:

Consideration factor one: the service life of the butterfly valve.

Butterfly valves can be used more than 10,000 times and can still be guaranteed to be “airtight” when closed.

Consider the second factor: pressure drop.

If the pressure drop is too large, it will increase energy consumption. Valves are not the only factor that causes pressure drop in piping systems, there are other factors that cause pressure drop: the fluid cross section of the pipe; the friction on the inner wall of the pipe.

Change of flow direction as it passes through the part. The fluid characteristics of the butterfly valve are three times or even higher than that of the globe valve, which is equivalent to 75% of the gate valve of the same size.

Consideration factor three: valve versatility.

Butterfly valves control and regulate piping systems by opening/closing and throttling/balancing. Butterfly valves have better “universality” than gate valves or globe valves. Because the butterfly valve can adopt various surface treatment technologies and select elastic material pipes, the butterfly valve has strong chemical corrosion resistance.

Consideration four: the weight of the valve.

The installation cost of light-duty butterfly valves is much less than that of heavy-duty cast iron valves:
For example, a 10-inch nominal diameter butterfly valve weighs 55 pounds, while a 10-inch cast iron gate valve weighs as much as 490 pounds. For the entire pipeline system, the installation cost saved by the butterfly valve is very considerable. In addition, the heavier the piping system, the stronger the piping support base is required, thus making the entire piping system more expensive. Therefore, considering the weight of the valve, the cost of the entire piping system can be saved

Consideration factor five: the size of the valve.

The space occupied by a butterfly valve is about 1/6 of that of a gate valve of the same size. And every additional cubic foot of building space means wasted costs. For example: a butterfly valve with a nominal diameter of 10 inches is approximately 21 inches high, while a gate valve with a nominal diameter of 10 inches is as high as 43 inches.

Consideration factor six: easy to operate.

The butterfly valve only needs to rotate 1/4 turn (90 degrees) from opening to closing. Gate and globe valves, on the other hand, require many turns to turn the valve from an open state to a closed state. The ease of opening or closing means there is no need to hire an overpaid operator to operate the butterfly valve.

Consideration seven: cost.

The cost of a butterfly valve is usually only 40% of the cast iron gate valve, not only the purchase cost is low, but also the installation cost is relatively low.

The last and most important factor: choose the right butterfly valve manufacturer – VALTECCN butterfly valve supplier, with many years of experience in production and sales of butterfly valves, and a perfect after-sales service team to solve any butterfly valve problems.
