Customer Testimonials & Cases

Perguntas frequentes

1. What is the difference between 304 and 316 stainless steel ball valves?

The main difference between 304 and 316 stainless steel ball valves is the material and performance. The 304 stainless steel works well in most environments as it is resistant to corrosive media, but it doesn’t handle chlorides (like salt) very well. Compared to 304 stainless steel, 316 contains added molybdenum, which enhances corrosion resistance, making it work better in hot, acidic, or salty conditions. It’s a bit more expensive than 304, but if you’re dealing with harsh environments, 316 is the better choice.

2. What is a CF8M ball valve?

CF8M is basically another way of saying 316L stainless steel. This material is more stable than 304 in corrosion and high-temperature conditions. CF8M ball valves are often used in applications like chemical plants or food processing, where durability and cleanliness are quite important.

3. How to choose the right ball valve for water lines?

When selecting your water pipe ball valve, keep these things in mind: material, specifications, sealing performance, connection type, and certification.

Material: Choose 304 or 316 stainless steel, depending on the corrosion resistance required.

Specifications: Match it to your pipe size, flow, and pressure.

Sealing Performance: Make sure it seals well to minimize leakage risks.

Connection Type: Choose threaded, flanged, or welded connections according to the installation environment.

Certification: Opt for products with quality certifications and reliable after-sales support.

4. Difference between full port and standard port ball valves?

A full-port ball valve has a opening equal to the pipeline diameter; this way the fluid passes through with almost no resistance. That’s why a full-port valve is suitable for applications requiring high flow rates or low flow resistance. A standard-port (or reduced-port) valve has a smaller opening, so it creates more resistance. This type of valve is often used in applications with limited installation space or where flow resistance is not a critical concern.

5. What factors affect stainless steel ball valve price?

Material: A 316 ss ball valve is more expensive than a 304 ss ball valve because of the added molybdenum.

Tamanho: Bigger or custom sizes cost more.

Brand: Famous brands and certified products usually charge extra.

Manufacturing Process and Standards: If it’s made with advanced methods or has international certifications, expect a higher price.

6. How to install a stainless steel ball valve?

Space: Make sure there’s enough room for operation it—don’t install it in restricted areas.

Cleanliness and Sealing: Clean the pipes and valve before installing so the seal works properly.

Manutenção: Conduct regular inspections to make sure it still seals well.

Safety Precautions: Wear protective gear during installation, and avoid mishandling under high pressure.
