FAQ

Q: Can fully welded ball valves be installed directly underground?

A: Yes. The valve body features no external leakage points, and its structure is designed for long-term underground service, thereby minimizing maintenance requirements.

Q: What is the typical service life?

A: Under normal operating conditions, they can function reliably for an extended period (typically over 20 years); the actual lifespan depends primarily on the specific media and operating conditions.

Q: Do you accept and fulfill large-volume orders?

A: Yes. We are equipped to handle mass production for specific projects, making us an ideal partner for large-scale engineering procurement and long-term supply agreements.

Q: What tests are performed on the valves before they leave the factory?

A: Every single valve undergoes rigorous pressure testing. Additionally, we can provide Non-Destructive Testing (NDT), Positive Material Identification (PMI), and third-party inspection reports upon request.

Q: Are these valves suitable for use in natural gas pipelines?

A: Yes. They are suitable for use with natural gas, oil and gas mixtures, and other high-pressure transmission media.

Q: Do you offer OEM services or custom non-standard solutions?

A: Yes. We can customize the dimensions, structural design, and actuation methods based on your specific technical drawings or operating conditions.

Q: Is the installation process complicated?

A: No, it is not complicated. The valves support both butt-weld and flanged connections, making them suitable for use in both new pipeline construction and existing pipeline retrofit projects.

Q: What is the Minimum Order Quantity (MOQ)?

A: We welcome small-batch trial orders and can also arrange order quantities flexibly to meet specific project requirements.
