Electric Stainless Steel Flange Butterfly Valves-DK56-FB-S
Electric Stainless steel flange butterfly valves are precision-engineered valves designed to control the flow of liquids and gases in industrial processes. Constructed from high-grade stainless steel, these valves offer exceptional resistance to corrosion, making them suitable for use in demanding environments where exposure to harsh chemicals or extreme temperatures is common. The flange connections facilitate easy installation and ensure a secure seal, minimizing the risk of leakage.
Electric Stainless steel flange butterfly valves are indispensable components in fluid control systems across various industries. Renowned for their durability, corrosion resistance, and efficient performance, these valves play a crucial role in regulating fluid flow in pipelines.
Model: Flange Butterfly Valves
Size Range: 2” to 16”
Pressure Range: 1.6MPa to 6.4MPa
Material: Stainless Steel 304/316
Description
The operation of stainless steel flanged butterfly valves is based on a simple yet effective principle. A disc, resembling a butterfly, is positioned within the valve body. When the valve is open, the disc allows fluid to flow freely through the pipeline. Conversely, when the valve is closed, the disc rotates to obstruct the flow, providing tight shut-off and precise control over the fluid flow rate. The actuation mechanism can be manual, electric, or pneumatic, depending on the application requirements.
In summary, stainless steel flanged butterfly valves are essential components in fluid control systems, offering reliable performance, durability, and versatility across a wide range of industrial applications. With their corrosion-resistant construction, precise operation, and easy installation, these valves provide an ideal solution for fluid control challenges in demanding environments.

Structures and Components:
- Body: The valve body is typically made of stainless steel, ensuring durability and resistance to corrosion. It provides a robust housing for the internal components and maintains structural integrity under high-pressure conditions.
- Disc: The disc, also fabricated from stainless steel, serves as the primary mechanism for regulating fluid flow. Its streamlined design minimizes pressure drop and turbulence, enhancing operational efficiency.
- Flanges: Stainless steel flanges are integrated into the valve body, allowing for easy connection to the pipeline and ensuring a leak-free seal.
- Stem and Actuator: The stem connects the actuator to the disc, transmitting the actuation force required to open or close the valve. The actuator, available in manual, electric, or pneumatic configurations, initiates the valve operation based on control signals received from external sources.
Stainless Steel Flanged Butterfly Valves Advantages:
- Corrosion Resistance: Stainless steel construction provides excellent resistance to corrosion, ensuring long-term durability and reliability.
- Versatility: Available in a wide range of sizes, pressure ratings, and end connections to suit diverse application requirements.
- Low Maintenance: Robust construction and minimal moving parts contribute to low maintenance requirements and extended service life.
- Precise Control: Butterfly valve design allows for precise flow modulation and throttling, enabling accurate control over fluid flow rates.
- Cost-Effectiveness: Stainless steel flanged butterfly valves offer a cost-effective solution for fluid control applications, delivering high performance and durability at competitive prices.
