Overview of AUT Butterfly Valve
AUT Butterfly Valve is one of the three lines of butterfly valves directly imported from Malaysia and is being distributed nationwide by Viva Joint Stock Company, an authorized distributor.
Belonging to the group of Malaysian butterfly valves with mid-range quality, AUT Butterfly Valve is trusted and widely chosen for many important domestic projects. Especially noteworthy are water supply systems for condominiums and commercial centers, which often prefer AUT brand products.
AUT Butterfly Valve is divided into three main product groups: lever, gear, and electric signal. Each product has its own unique design features, and they all use materials such as cast iron, stainless steel, and rubber in the manufacturing process.
Viva offers the most affordable AUT Butterfly Valves in the market
Currently, there are various brands of butterfly valves available in the market, and as a result, the prices for each brand vary significantly. So, how can we evaluate a product’s affordability? The only way is to compare the price you pay with the quality the product provides to consumers.
As you may already know, the lowest-quality butterfly valves are often the ones produced and imported from China. This is evident in their relatively poor performance and thin details compared to other butterfly valve lines. Chinese butterfly valves are always lighter in weight than other types.
Returning to AUT Butterfly Valves, they ensure high quality with thicker details compared to other brands, and their prices are extremely reasonable.
The price of AUT Butterfly Valves is always lower than those from South Korea by 25% to 30%. Furthermore, the prices at Viva are lower than other suppliers by 20% to 25%. This is because our company imports the products directly from the factory, without involving any intermediaries, both domestically and internationally.
VAN BƯỚM AUT’s wings are made of stainless steel
For the AUT brand, instead of producing stainless steel butterfly valves, they only manufacture cast iron butterfly valves. As you may already know, the quality and corrosion resistance of cast iron materials are never comparable to stainless steel materials, and this directly affects the applicability of the product.
However, in order to increase durability and usability of the product in different situations, AUT has manufactured the valve disc, also known as the butterfly disc, using stainless steel.
The valve disc is a component that directly contacts the fluid throughout the product’s life cycle, during both usage and operation.
With the butterfly wings made of stainless steel, the product is also known as the cast iron body with stainless steel wings butterfly valve. This is considered the national design for current butterfly valve models and is widely chosen for use.
Classification of AUT butterfly valve products
In the previous section, I introduced to you how AUT butterfly valves are divided into three main product groups. What are the differences among these products? Let’s take a closer look at the following presentation to better understand each line of AUT products.
AUT Hand Lever Butterfly Valve
The first product I want to introduce to you is the line of products that use hand levers for operation. When it comes to hand lever butterfly valves, you are probably familiar with them. This type of butterfly valve has a lever that users can easily replace to operate it.
The highlight of hand lever butterfly valves is that they are easy to use and have much lower investment costs compared to other types of butterfly valves.
They can be applied in various working conditions, from systems with roofs to outdoor systems exposed to direct sunlight and rain.
AUT Gear Operated Butterfly Valve
If you prefer not to use a hand lever that requires a lot of force to operate, you can switch to using products that use gear operators.
The advantage of gear operators is that they provide a smooth opening and closing experience, even when using products with sizes up to DN500 or DN600.
With the mentioned advantages, the price of gear operated butterfly valves is generally higher than those using hand levers.
Electric and Pneumatic Control Butterfly Valve
The electric and pneumatic control butterfly valve is a different variant of the conventional AUT butterfly valve. Instead of using a lever or handwheel, as mentioned above, you can now use additional electric and pneumatic control units from a third-party brand. The purpose of this modification is to enable you to operate more products and save operational time compared to mechanical-based products.
Compared to pneumatic control, electric butterfly valves offer smoother operation without generating noise. With a voltage of 220v available everywhere, it allows for easier installation and implementation of the product.
On the other hand, with pneumatic butterfly valves, although they are cost-effective, you need an air compressor to operate the product.
Signal Electric AUT Butterfly Valve
Unlike products using conventional electric control units, the signal electric AUT butterfly valve is designed with a three-wire configuration to provide feedback to the control center about the device’s open and closed status.
These signal electric products are mainly used for fire protection and firefighting systems. The distinguishing feature is the red color coating from inside to outside, aiming to synchronize the system’s operation more effectively.
Testing and Maintenance of AUT Butterfly Valves
After a prolonged period of using the product, sediment will inevitably accumulate on the valve body and butterfly disc, significantly affecting the valve’s operation.
At this point, the most important task is to inspect and maintain the product by cleaning its components, bringing the butterfly valve back to its optimal working condition.
There are two ways to clean the product, but before performing any cleaning, make sure to disassemble the parts to simplify and facilitate the process, avoiding any interference with other components.
Use a grinding machine to clean the specific parts, especially the valve disc and body. Then proceed to reassemble the components together. After assembly, it is necessary to check the tightness of the device by putting it in the closed position and pouring water to test for leakage. If no water leakage is observed, the valve is considered good.
