Stainless Steel Butterfly Valve
The Application of Stainless Steel Butterfly Valve
Metal Seated Butterfly Valve offers robust performance in demanding applications. Unlike resilient seated butterfly valves, which use elastomeric seals, metal seated valves utilize metal-to-metal sealing for enhanced durability and reliability. Constructed with high-quality A105 material or its variant A105N, these valves comply with industry standards such as API 607 for fire safety and Trim 12 material specifications. Cameron, a trusted brand, offers a range of options including SMS butterfly valves and Victaulic butterfly valves tailored for specific needs. With features like split butterfly valves and compatibility with A350 LF2 materials, Cameron’s offerings ensure optimal performance and longevity in critical processes.
Features of Stainless Steel Butterfly Valve
- Tight Seal: Our stainless steel butterfly valve uses a combination of seating surface offsets and graphite lamination to ensure a tight and consistent seal, requiring minimal torque to operate.
- Anti Blowout Design: The valve features a double anti-blowout design that meets API 609 and ASME B31.1 requirements. This design prevents stem dislocation both internally and externally, ensuring safety and compliance.
- Zero Leakage: Utilizing laminated seal rings, our stainless steel butterfly valve is engineered to self-align, achieving zero leakage according to API 598 standards.
- Guided Shaft: The valve’s shaft is fully guided by shaft bearings and gland followers, reducing side load caused by line pressure thrust. This design enhances stability and longevity of the valve operation.
The Parameter of Stainless Steel Butterfly Valve
- Material: Constructed from durable stainless steel, resistant to corrosion and wear in various operating environments.
- Seating Surface: Utilizes triple offset design for the seating surface, enhancing sealing performance and minimizing wear over time.
- Size Range: Available in a range of sizes to accommodate different flow rates and pipeline requirements, from small diameters to larger industrial applications.
- Pressure Rating: Designed to withstand high pressures, typically rated up to ANSI Class 150 or higher, ensuring reliability in demanding conditions.
- Temperature Range: Capable of operating within a wide temperature range, suitable for both hot and cold fluid applications.
- Actuation Options: Compatible with various actuation methods, including manual handwheel, lever, pneumatic, or electric actuators, providing flexibility in valve operation.
- End Connections: Offers versatility with a selection of end connection options such as wafer, lug, or flanged ends, facilitating easy integration into different piping systems.
- Standards Compliance: Meets industry standards such as API, ASME, and ANSI, ensuring quality, performance, and safety in accordance with regulatory requirements.
The Operation Theory of Stainless Steel Butterfly Valve
- Material: Constructed from durable A216 SCB material, ensuring robustness and resistance to corrosion.
- Size Variants: Available in diverse sizes, from small 1/2 inch butterfly valves to larger 5 and 6 butterfly valves, catering to different flow requirements.
- Flow Regulation: The valve controls flow by rotating a disc within the pipe. When open, the disc aligns with the flow direction, allowing fluid passage. Conversely, closing the valve involves turning the disc perpendicular to the flow, restricting or stopping fluid flow.
- Triple Offset Design: Employing a triple offset design ensures tight sealing and minimizes wear, enhancing longevity and reliability.
- Low Torque Operation: Requires minimal torque for operation, facilitating manual handling or integration with automated systems.

Relevant Information about Stainless Steel Butterfly Valve
- Shaft Seal: Utilizes a high-performance seal to prevent leakage along the shaft, often consisting of materials like PTFE or graphite.
- Driving System: Operated manually through a handwheel or lever, or automated using pneumatic, electric, or hydraulic actuators. The driving system provides the necessary force to rotate the valve disc for opening, closing, or modulating flow.
- Disc and Stem: The disc is typically made of stainless steel or alloy steel, providing durability and corrosion resistance. The stem, also made of stainless steel or alloy steel, connects the disc to the actuator and ensures smooth operation.
- Universal Joint: Butterfly valves generally do not incorporate universal joints. Instead, they use a simple rotary motion for operation.
Overall, the design of a Metal Seated Butterfly Valve focuses on ensuring reliable sealing, ease of operation, and compatibility with various driving systems for efficient flow control in industrial applications.
