Frequently Asked Questions

Q: What is cast steel wafer type butterfly valve?

A: Cast steel wafer type butterfly valve is a butterfly valve made of cast steel with a wafer-type connection structure. The closing part (valve disc or butterfly plate) of the butterfly valve is disc-shaped, which is driven by the valve stem to rotate around its own axis in the valve body to achieve the purpose of opening and closing. The wafer-type connection means that the valve is directly clamped between the pipe flanges without the need for additional bolted connectors, making the structure more compact.

Q: What materials does the cast steel wafer type butterfly valve mainly consist of?

A: Valve body material: The main material of the valve body is cast steel, which has high strength and hardness, can withstand high pressure and temperature, and has good corrosion resistance. The choice of cast steel material depends on the characteristics of the medium and the requirements of the working environment.
Butterfly plate material: The butterfly plate is a key component of the butterfly valve, which rotates with the valve stem to control the flow of the medium. The butterfly plate material is usually matched with the valve body material, and is also made of cast steel or stainless steel to ensure its strength and corrosion resistance.
Sealing material: For occasions requiring good sealing performance, butterfly valves usually use soft sealing materials such as rubber rings or elastic sealing elements. These materials can fit the valve seat tightly to form an effective seal. In high temperature, high pressure or corrosive media, butterfly valves may use hard sealing materials such as metal sealing rings or coatings. These materials have high hardness and wear resistance and can maintain sealing performance under harsh working conditions.
Stem material: The valve stem is a component that connects the butterfly plate and the actuator, and it needs to withstand a certain amount of torque and wear. Therefore, the valve stem is usually made of corrosion-resistant and wear-resistant materials such as stainless steel.
Flanges and fasteners: The wafer-type butterfly valve is connected to the pipeline through flanges. The materials of flanges and fasteners also need to be selected according to the characteristics of the medium and the working environment. Usually, they are also made of cast steel, stainless steel and other materials.

Q: What are the advantages of the cast steel wafer type butterfly valve?

A: First, its short structure length can save raw materials and installation space, while effectively supporting the strength of the pipeline.
Second, the valve block moves correctly and the gate is squeezed quickly to ensure the effective sealing of the valve.
Third, it has triangular support materials to ensure the required mechanical properties.
Fourth, it can design V-shaped, triangular, or pentagonal interfaces according to different working conditions to meet the needs of various flow regulation.
Fifth, there is no groove at the bottom to ensure no slag and full flow.
Sixth, we strictly implement the API598 test standard and implement 100% positive and negative double pressure tests on each product to ensure that the products delivered to customers are 100% qualified products.

Q: How to choose a suitable cast steel wafer type butterfly valve?

A: Body material: Cast steel is a commonly used body material with good strength and corrosion resistance. However, depending on the specific requirements of the medium, stainless steel or other alloy materials may also need to be considered.
Sealing material: Selecting the right sealing material is crucial to ensuring the sealing performance of the butterfly valve. For corrosive media, special sealing materials such as metal rings or special rubber may be required.
Structural form: The wafer-type butterfly valve has the advantages of simple structure, small size and light weight. At the same time, consider the sealing form (such as elastic seal or metal seal) and valve stem form (such as ordinary valve stem or valve stem with worm gear reducer) of the butterfly valve to meet specific application requirements.
Drive mode: Select the appropriate drive mode according to the application requirements, such as manual operation, electric, pneumatic, etc. For occasions that require remote operation or automated control, electric or pneumatic drive is more suitable.
Maintainability: Consider the maintainability of the butterfly valve, including whether it is easy to replace the seal, whether it is easy to clean and inspect, etc. Some butterfly valves are designed with the function of quick replacement of seals, which can greatly shorten the maintenance time.

Q: What factors affect the durability of cast steel wafer type butterfly valve?

A: Valve body material: Cast steel is used as the valve body material, and its quality directly affects the overall strength and corrosion resistance of the valve. High-quality cast steel materials can resist the erosion of the medium, reduce internal corrosion and wear of the valve body, and thus extend the service life of the valve.
Sealing material: The selection of sealing materials is equally important. High-quality sealing materials have good high temperature resistance, corrosion resistance and wear resistance, which can ensure that the valve can still maintain good sealing performance under harsh working conditions.
Casting process: Factors such as control accuracy, temperature control, and alloy composition in the casting process will affect the quality of the casting. Reasonable casting process can reduce defects inside the casting, such as shrinkage holes, cracks, pores, etc., thereby improving the durability of the valve.
Machining accuracy: The machining accuracy of the valve directly affects its sealing performance and operational stability. High-precision machining can ensure that the various components of the valve fit closely, reducing leakage and wear.
Operating frequency: The operating frequency of the valve will also affect its durability. Valves that are frequently opened and closed need to withstand greater mechanical stress and wear, so more durable materials and structures need to be selected.
Sealing structure: Reasonable sealing structure design can reduce leakage and wear, and improve the sealing performance and durability of the valve. For example, butterfly valves with metal seals generally have a longer service life than butterfly valves with elastic seals.

Q: Will cast steel wafer type butterfly valve rust?

A: The corrosion resistance of cast steel is a key factor affecting whether the butterfly valve will rust. If the quality of cast steel is poor or the corrosion resistance is poor, the butterfly valve will be easily corroded by the medium or environment during use and rust. In addition, regular maintenance and care are important measures to prevent butterfly valves from rusting. If the dirt on the surface of the butterfly valve is not cleaned in time or appropriate anti-corrosion measures are not taken, the protective layer on the surface of the butterfly valve may be destroyed, thereby accelerating the rusting process.

Q: What should be paid attention to during the use of the cast steel wafer type butterfly valve?

A: First of all, the operation should be carried out in accordance with the valve's instruction manual to avoid damage to the valve due to excessive force or improper operation. You should regularly check the valve's operating torque to ensure that it is within the normal range.
Moreover, you should pay attention to factors such as the temperature, pressure, and corrosiveness of the medium to avoid exceeding the rated range of the valve. For media containing solid particles, the inside of the valve should be cleaned regularly to prevent blockage or wear.
Furthermore, you should also regularly check the valve's sealing performance to ensure that there is no leakage. If a leak is found, it should be handled and the seal replaced in a timely manner.
In addition, you should wear appropriate safety protection equipment during operation, such as gloves, goggles, etc. Avoid open flame operations or storing flammable and explosive items near the valve.

Q: What are the limitations of cast steel wafer type butterfly valve?

A: Sealing performance limitation: Although the wafer butterfly valve has a certain sealing performance in the closed state, its sealing performance may be insufficient in high-pressure and high-demand process flows, and it cannot completely isolate the flow path between the media, resulting in leakage.
Large operating torque: With the increase in the number of valve switches and the extension of the operating time, especially in the case of large diameters, the operating torque of the wafer butterfly valve will gradually increase. This not only increases the difficulty of operation, but may also affect the normal operation and production efficiency of the equipment.
Wear resistance needs to be improved: The wafer butterfly valve will be affected by the erosion and wear of the medium during use. When used for a long time in some corrosive media environments or those containing solid particles, it is easy to be damaged or even fail. This limits its application range and increases maintenance costs to a certain extent.
Limited scope of application: The wafer butterfly valve is mainly suitable for medium and low pressure and small and medium diameter pipelines, and is generally not suitable for high pressure and large diameter pipelines. This limits its use in certain specific application scenarios.

Q: Is cast steel wafer type butterfly valve easy to use?

A: Simple structure: Compared with some complex valve types, the structure of cast steel wafer type butterfly valve is relatively simple, mainly composed of valve body, valve plate, valve stem and seals. This simple structure makes the valve operation more direct and convenient when opening and closing.
Easy operation: Cast steel wafer type butterfly valve usually adopts rotary operation, which drives the valve plate to rotate in the valve body by rotating the valve stem, thereby realizing the opening and closing of the valve. This operation method is usually relatively light and does not require excessive force to complete the operation, thereby improving the convenience of use.
