Frequently Asked Questions (FAQ)
-
Q: What does "Compliant with CB/T3191" mean for my application?
A: CB/T3191 is a Chinese national standard specifically for marine valves. Compliance ensures the valve is designed, manufactured, and tested to meet the safety, performance, and material requirements suitable for marine environments, offering you assurance of its suitability for shipboard use. -
Q: Are the gaskets included compatible with all media?
A: The standard gaskets provided are typically selected for compressed air service. For applications involving other media (e.g., oil, chemicals), please specify during inquiry so we can supply the appropriate gasket material (like NBR, EPDM, or PTFE) for optimal compatibility. -
Q: Can this valve be used for gases other than compressed air?
A> While designed for compressed air, it can often be used for other inert gases (like nitrogen) within the specified pressure and temperature ratings. However, for aggressive or specific gases, consultation on material compatibility (especially seal materials) is required. -
Q: Is the installation manual available in languages other than English?
A: The standard manual is in English. Manuals in other languages may be available upon request, depending on the order volume and specific requirements. -
Q: Do you offer valves with different end connections, like ANSI flanges?
A: Yes. We offer flexibility in connection standards. While standard offerings align with common Chinese standards (GB), valves with ANSI, JIS, or other flange standards, as well as NPT or BSP threads, can be provided. Please specify your connection requirements when inquiring. -
Q: What is the lead time for a custom order (e.g., special size or material)?
A: Lead times vary based on the complexity and quantity of the order. For standard configurations, shipment is typically faster. For customized orders, we will provide a specific production timeline upon confirmation of your technical specifications. -
Q: How do I determine the correct valve size (DN) for my piping system?
A> The valve's Nominal Diameter (DN) should match the inner diameter of your pipeline. Please provide your pipe size and system pressure details. Our technical team can assist in selecting the most suitable valve size and pressure rating for your application. -
Q: What kind of after-sales support do you provide?
A: We provide technical support for installation and operation. Should any issues arise related to material or workmanship under normal use, please contact us with the product details for assistance.
