Product Description

A stainless steel butterfly valve is a type of valve used to regulate the flow of a fluid through a pipe. It consists of a disk, known as the butterfly, which rotates on a shaft. When the valve is fully open, the disk is parallel to the direction of flow, allowing for unrestricted passage of the fluid. When the valve is closed, the disk is perpendicular to the flow, blocking it completely.

Stainless steel butterfly valves are often preferred in applications where hygiene and cleanliness are important, as stainless steel is easy to clean and sterilize. They are also known for their durability and longevity, making them a reliable choice for various industrial processes.

 

 

Stainless Steel butterfly valves offer several advantages over other types of butterfly valves, particularly those with elastomeric seals:

High Temperature Resistance: Metal seals can withstand higher temperatures compared to elastomeric seals. This makes metal seal butterfly valves suitable for applications involving high-temperature fluids or environments.

Chemical Compatibility: Metal seals are more chemically resistant than elastomeric seals. They can handle a broader range of fluids, including corrosive and abrasive media, without degradation or deterioration.

Longer Service Life: Due to their robust construction and resistance to wear and tear, metal seal butterfly valves tend to have a longer service life compared to valves with elastomeric seals. This can result in lower maintenance costs and reduced downtime for replacement or repair.

Tight Shutoff: Metal seals provide a tighter shutoff compared to elastomeric seals, especially in high-pressure applications. This ensures better control over flow rates and minimizes leakage, enhancing overall system efficiency.

The stainelss steel butterfly valve regulates flow by rotating the disc within the flow path. When the valve is fully open, the disc is positioned parallel to the flow direction, allowing fluid to pass through with minimal obstruction. Conversely, when the valve is closed, the disc is rotated perpendicular to the flow, blocking the passage of fluid.

Butterfly valves are commonly applicating in a variety of industries, including:

1. Oil and Gas: Triple offset butterfly valves applicate in the oil and gas industry. For pipeline isolation, compressor stations, and refining processes.
2. Chemical: Triple offset butterfly valves are popular in chemical plants for applications. Such as corrosive and abrasive fluid handling, high-temperature services, and toxic gas handling.
3. Power Generation: Triple offset butterfly valves play an important role in power generation. For applications such as steam isolation, turbine bypass, and cooling water control.
