 316 Stainless Steel Butterfly Valve

Product Overview:

The 316 Stainless Steel Butterfly Valve is engineered for superior performance in demanding applications. It is constructed from 316 stainless steel, which offers exceptional resistance to corrosion and durability. This valve is available in both hard-sealed and soft-sealed versions to meet various application requirements.


316 Stainless Steel Material:

– Corrosion Resistance: 316 stainless steel is renowned for its excellent corrosion resistance. It withstands harsh environments, including exposure to chlorides, acids, and other corrosive substances. This material is particularly effective in marine and chemical processing applications.

– Durability: 316 stainless steel is known for its strength and durability. It maintains its structural integrity and appearance even under extreme conditions.


Sealing Types:

– Hard Seal: Hard-sealed butterfly valves feature a metal-to-metal seal. This design is suitable for high-temperature applications. It provides a robust seal against high pressures. The hard seal is ideal for applications where leakage control is critical and the valve is subject to severe conditions.

– Soft Seal: Soft-sealed butterfly valves are lined with PTFE (Polytetrafluoroethylene) to provide a tight seal. PTFE is known for its excellent chemical resistance and low friction properties. This sealing type is ideal for applications involving corrosive fluids. It ensures a high level of sealing performance.


Media and Working Conditions:

– Media Compatibility: The 316 stainless steel butterfly valve is versatile. It can handle a wide range of media, including water, air, gases, steam, and various chemicals. The choice of sealing type further enhances compatibility with specific media.

– Working Conditions: This valve performs effectively in various working conditions:

– Temperature Range: The valve operates efficiently within a wide temperature range. The hard-sealed version can handle higher temperatures. The soft-sealed version is suitable for applications within the PTFE’s temperature limits.

– Pressure Range: It is designed for both medium and high-pressure environments. The 316 stainless steel construction ensures the valve maintains its performance under different pressure conditions.

– Chemical Exposure: The valve’s material and sealing options make it suitable for environments with exposure to aggressive chemicals and corrosive substances.


Summary:

The 316 Stainless Steel Butterfly Valve offers robust performance and excellent corrosion resistance. It features high-quality 316 stainless steel construction. It is available in both hard-sealed and soft-sealed versions, providing flexibility for various applications. The hard seal is ideal for high-pressure and high-temperature conditions. The soft seal, lined with PTFE, is perfect for corrosive media. This valve is suitable for a broad range of media and working conditions, making it a reliable choice for industrial applications requiring durability and resistance to harsh environments.
