Product Selection Differences for Cast Iron Butterfly Valves

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

1. Size: Valve size is an important consideration to ensure it fits your piping system requirements.

2. Pressure Rating: Ensure the valve's pressure rating matches your system's pressure specifications to prevent leaks or malfunctions.

3. Material: Cast iron is durable and resistant to wear, but consider the specific type of cast iron used in the valve construction for corrosion resistance.

4. Seat Material: The seat material affects the valve's sealing capabilities and longevity. Options include EPDM, Buna-N, PTFE, and others.

5. Disc Type: Choose between different disc materials (cast iron, stainless steel, ductile iron) based on the application requirements for corrosion resistance and durability.

6. Operating Mechanism: Consider whether you need a manual handle, gearbox operator, pneumatic actuator, or electric actuator for valve operation.

7. End Connection: Check the valve's end connections (wafer, lug, flanged) to ensure compatibility with your piping system.

8. Certifications: Make sure the valve meets relevant industry standards and certifications to ensure quality and compliance.

9. Price: Evaluate the cost of the valve in relation to your budget and the overall value it provides for your specific application.

Considering these factors will help you select the most suitable cast iron butterfly valve for your industry needs.
