Product Selection Differences for Standard Butterfly Valves

When selecting Standard Butterfly Valves, there are several key differences to consider:

1. Size and Pressure Rating: Butterfly valves come in various sizes and pressure ratings. Make sure to choose the size and pressure rating that matches your application requirements.

2. Material: Consider the material of the valve body and disc. Common materials include cast iron, ductile iron, carbon steel, stainless steel, and PVC. The material should be compatible with the fluid being controlled and the operating conditions.

3. Seat Material: The seat material affects the sealing performance of the valve. Seats are typically made of materials like EPDM, Buna-N, PTFE, and Viton. Choose a seat material that is suitable for your application in terms of temperature, pressure, and chemical compatibility.

4. Actuation: Butterfly valves can be operated manually or with actuation such as electric, pneumatic, or hydraulic actuators. Consider the type of actuation that best suits your operational needs.

5. End Connections: Butterfly valves come with different end connections, such as wafer, lug, and flanged. Ensure the end connection type is compatible with your piping system.

6. Flow Control: Some butterfly valves offer features for flow control, such as throttling capabilities or a V-port design for modulating flow. Consider if these features are necessary for your application.

7. Certifications and Standards: Check if the valve meets industry standards and certifications, such as API, ANSI, or ISO standards, to ensure quality and reliability.

By considering these factors, you can select the Standard Butterfly Valve that best fits your specific application requirements.
