The eccentric butterfly valve is a versatile and cost-effective solution for one-way flow systems. It restricts backflow and prevents unwanted mixing of fluids. Its lightweight design and durable construction make it ideal for various applications, including water treatment plants, HVAC systems, and oil & gas industries. The valves are available in different models, each of which is suitable for a wide range of pressure and temperature ratings. To help you choose the right eccentric butterfly valve for your application, this article will discuss some of the most common types.
The single-eccentric structure of this type of valve enables the disc to move away from the seat with a non-rubbing motion during the opening process. This reduces the scraping between the valve plate and the soft seat, which extends its seating life. This type of valve also has low operating torque and a high sealing capacity.
The double-eccentric butterfly valve is a highly efficient model that offers excellent performance and sealing capability for a wide range of fluids and gases. Its unique design allows the disc to move away from the seat in a non-rubbing cam-like motion, minimizing seat damage and ensuring a tight seal against the seat even when under high pressure.
Additionally, the double-eccentric butterfly valve provides a higher level of safety in operation than other types of butterfly valves. This is because the eccentric mechanism enables the disc to separate from the seat during opening and closing, preventing it from damaging the soft valve seat. The PTFE liner also helps to minimize the risk of leakage and wear, extending its lifespan.
These valves are highly durable and can withstand acidic fluids, high pressures, and temperatures. They are ideally suited for demanding applications such as pipelines for oil and gas, industrial processing, and marine transportation. Moreover, they are easy to install and operate, requiring minimal installation space and reducing maintenance costs.
Compared to linear valves, eccentric butterfly valves offer lower actuating moments and can be used for larger diameters. They also require less space in pipe systems, allowing them to be installed in tight spaces. The double-eccentric shaft also eliminates the need for a thrust bearing, which makes it a more cost-effective option.
