Question 1

Are you a manufacturer or a trading company?

Accepted Answer

We are a professional valve manufacturer located in Wenzhou, China, with over 15 years of experience. We welcome factory visits.

Question 2

What certifications do you hold?

Accepted Answer

We are ISO, CE, EAC,TS certified. Our products strictly comply with ANSI, DIN, JIS, BS, and GB standards.

Question 3

Do you offer OEM/ODM services?

Accepted Answer

Yes. We can customize valve body logos, materials (e.g., CF8M, WCB), connection types, and pressure ratings according to your drawings or samples.

Question 4

For Ball Valves, do you offer both floating and trunnion-mounted designs?

Accepted Answer

Yes. We supply Floating Ball Valves (for smaller sizes, e.g., DN15-DN200) and Trunnion-Mounted Ball Valves (for larger sizes, e.g., DN200 and above) to reduce operating torque and ensure stability.

Question 5

What is the difference between Rising Stem and Non-Rising Stem Gate Valves?

Accepted Answer

We manufacture both types. Rising Stem Gate Valves allow operators to visually see if the valve is open or closed (common in above-ground installations), while Non-Rising Stem Gate Valves are suitable for underground or limited vertical space applications.

Question 6

Do your Globe Valves offer good shut-off capability?

Accepted Answer

Absolutely. Globe Valves are specifically designed for throttling and regulating flow. They provide superior tight shut-off compared to gate valves but have a higher pressure drop. We ensure the disc and seat are precisely machined for a perfect seal.

Question 7

Which type of Check Valves do you recommend for low-pressure systems?

Accepted Answer

For low-pressure or non-return applications where water hammer is a concern, we recommend our Swing Check Valves or Wafer Check Valves. They offer low cracking pressure and minimal flow resistance.

Question 8

What mesh size do you use for Y Strainers?

Accepted Answer

Our standard Y Strainers come with a 40-mesh or 80-mesh stainless steel screen. Custom mesh sizes (e.g., 60-mesh, 100-mesh) are available upon request for filtering finer particles.

Question 9

How do you protect valves during shipping?

Accepted Answer

We apply anti-rust oil, use plastic film wrapping, and install end protectors on all connection ends. Larger valves are packed in reinforced plywood cases to prevent damage during sea freight.

Question 10

Can I get a sample for testing?

Accepted Answer

Yes, sample orders are accepted. The sample cost is refundable once you place a bulk order.
