Product Selection Differences for Butterfly Valves

When selecting butterfly valves, there are several key factors to consider to ensure they meet your specific application requirements. Some of the key differences to consider among available options include:

  1. Type of Butterfly Valve: There are different types of butterfly valves, such as resilient-seated, high-performance, and triple-offset butterfly valves. Each type is suitable for different applications based on factors like pressure, temperature, and flow control requirements.

  2. Operating Mechanism: Butterfly valves can have different operating mechanisms, such as manual, pneumatic, electric, or hydraulic actuation. The choice of operating mechanism depends on factors like the level of automation required, operating conditions, and control preferences.

  3. Size and Pressure Rating: Butterfly valves come in various sizes and pressure ratings. It is essential to select a valve size and pressure rating that is suitable for your specific flow requirements and system pressure.

  4. Materials of Construction: Butterfly valves can be made from different materials such as stainless steel, carbon steel, ductile iron, and exotic alloys. The material of construction should be selected based on factors like fluid compatibility, temperature range, and corrosion resistance requirements.

  5. Sealing Design: The sealing design of butterfly valves can vary, including resilient-seated, high-performance, and metal-seated options. The choice of sealing design depends on factors like the type of media, pressure, and temperature of the application.

  6. Flow Control Requirements: Consider the flow control requirements of your system, such as throttling or on/off service. The design and characteristics of the butterfly valve should be suitable for achieving the desired flow control performance.

  7. Standards and Certifications: Ensure that the butterfly valve meets industry standards and certifications relevant to your application, such as API, ANSI, ISO, or specific industry standards for safety and performance.

By considering these key differences among available butterfly valve options, you can select the most suitable valve for your specific application needs.
