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

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 5

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 6

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 7

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 8

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 9

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.
