Valves: FAQ

How do I ensure the thread size matches my local pipes?

Always verify the thread standard (NPT vs. BSP) and measure the inner diameter in millimeters. Check the seller's conversion chart to ensure compatibility with your regional plumbing standards.

How can I verify the material quality of the valve?

Look for material certifications like SUS304 for stainless steel or CW617N for brass. Genuine sellers will provide weight specifications and chemical composition details in the product description.

What technical specs indicate a high-durability valve?

Check the maximum pressure rating (PN) and temperature range. A PN16 rating is standard for home use, while higher ratings are better for industrial applications.

What should I check regarding shipping for heavy valve orders?

For bulk or heavy brass orders, look for listings with tracked shipping to avoid delays. Ensure the seller uses reinforced packaging to prevent thread damage during transit.
