Step 3: Choose the Right Size

The valve size is critical for proper flow and system performance. Calculate the diameter based on pipe size and flow rates. Ensure that the selected valve matches the pipeline system.

Step 4: Select Material and Coatings

Choose a valve material that suits your environment and application demands:

• Cast Iron: Commonly used for water applications; economical and durable.
• Ductile Iron: Offers higher strength than cast iron and is more resistant to cracking.
• Stainless Steel: Suitable for corrosive environments; provides excellent resistance to rust and chemicals.

Additionally, consider protective coatings to enhance the valve's longevity and performance.

Step 5: Evaluate Valve Design Features

Pay attention to the design features that affect operation and maintenance:

• Actuation Method: Determine if you need manual or automated actuation based on your control needs.
• Sealing Mechanism: Look for durable sealing options that minimize leakage.
