Introduction to Cast iron butterfly valve with stainless steel disc
Cast iron butterfly valve with stainless steel disc is a type of butterfly valve where the body component is cast from cast iron material, while the disc component is made of stainless steel. That’s why the name “Cast iron butterfly valve with stainless steel disc” is used by both sellers and buyers to refer to such products.
Compared to products made entirely of stainless steel or plastic and cast iron, the cast iron body stainless steel butterfly valve is widely chosen for use. This is because it ensures two factors: durability and applicability in today’s working systems.
Considered as one of the products that provides users with many options and various designs, this is also the reason why users have always trusted and used the product.
Key Advantages of the Cast Iron Body Stainless Steel Butterfly Valve
Cast iron body stainless steel butterfly valves always ensure work efficiency, even at working temperatures up to 120°C and pressures that can reach PN10.
They come in diverse designs, ranging from products used in high-pressure systems to those used in low-pressure systems.
The product can be operated through various different working control mechanisms, depending on the user’s preference and practical usage needs.
Cast iron body stainless steel butterfly valves are of great interest to many brands and manufacturers, as almost no brand in the world overlooks this design during the butterfly valve manufacturing process.
There are no limitations on size; however, for large products with sizes larger than dn400, they are usually not readily available like smaller-sized models. Instead, they require ordering time from the factory to manufacture products with specifications that meet the system’s usage needs.
One end of the valve stem is designed in a square shape, allowing for better connections with electrical and pneumatic control devices compared to circular stem designs.
Viva specializes in importing cast iron body stainless steel butterfly valves
Currently, there is no local brand in Vietnam that can produce butterfly valves. The majority are still manufacturing products made of copper and plastic. Therefore, cast iron body or 100% stainless steel and cast iron butterfly valves are imported from abroad.
Our company specializes in importing various types of butterfly valves, including cast iron body stainless steel butterfly valves, from the following countries.
Imported Cast Iron Body Stainless Steel Butterfly Valve from China
China is a country with a highly developed economy in various industrial sectors, including the industrial valve and pipe fittings industry.
Although it may not have many
famous brands, China is capable of producing all types of industrial valves available today, from products used for water systems to products used for compressed air systems.
The products imported from China have very affordable prices. If you don’t focus too much on quality, I am confident that these products will be suitable for your project.
Stainless Steel Butterfly Valve with Cast Iron Body, Imported from South Korea
While the strength of Chinese valves lies in their affordable price, South Korean butterfly valves have their strength in terms of quality.
On the modern production line, products imported from South Korea are highly regarded for their high level of finished product processing.
Currently, Viva company only imports butterfly valves with cast iron bodies and stainless steel wings from South Korea, specifically from the Samwoo brand. In reality, South Korea has many butterfly valve brands, such as Wonil, YDK, and Joeun. However, compared to the products from Samwoo, the butterfly valves from those three brands are slightly inferior, as Samwoo brand only produces butterfly valves exclusively.
Stainless Steel Butterfly Valve Imported from Malaysia
Above, I shared with you a line of affordable products and a line of expensive products. Now, let’s continue to introduce Viva’s product line by exploring the butterfly valves imported from Malaysia.
The advantage of products imported from Malaysia is that their prices are not as high as those of South Korean butterfly valves, nor as cheap as Chinese butterfly valves, so their quality is higher.
It is no coincidence that apartment buildings or fire protection systems nationwide prefer to use products from this country.
Rubber Gasket on Stainless Steel Butterfly Valve
Despite being a design that many brands are interested in and manufacture, this shows us that the product has a diverse range of origins. However, there are common features among products from different brands and countries.
The first common feature is that all rubber gaskets use EPDM material for manufacturing. This is a material with the advantage of high elasticity and resistance to tearing during operation.
This ensures that the stainless steel butterfly valve always maintains an absolute seal, without the risk of fluid leakage through the opposite end when the valve is in the closed position.
Things to Know When Using Cast Iron Butterfly Valve with Stainless Steel Disc
To ensure that no unexpected damage or malfunction occurs during use, you need to be aware of the following:
This product should not be used for chemical systems, especially highly corrosive saltwater systems.
It allows for bidirectional flow and can be installed in any working position, unlike one-way valves or filters that require specific installation directions.
If you are using electrically connected products, you need to provide a protective cover to ensure the safety of the operator.
Choose a cast iron butterfly valve with a stainless steel disc that has suitable working parameters for the internal system. The parameters of the butterfly valve should always be higher than those of the factory system.
