Frequently Asked Questions
-
Q: What is the difference between your CB/T4480 valve and standard bronze ball valves?
A: Our valve is manufactured specifically to the Chinese marine standard CB/T4480, which includes stricter material requirements, tighter tolerances, and specific testing procedures for marine environments. It also comes with a mill test report for material certification. -
Q: Can the actuator be replaced with a manual handle or pneumatic actuator?
A: Yes, we offer the same valve body with manual gearbox or pneumatic actuator options. The electric version is compatible with standard mounting flanges (ISO 5211), making it easy to retrofit. -
Q: What voltage options are available for the electric actuator?
A: Standard voltages are AC 220V and DC 24V. Other voltages (AC 110V, DC 12V, 380V, etc.) are available upon request. Please specify your requirement when ordering. -
Q: Is the valve suitable for use with potable water?
A: Yes, bronze is an approved material for potable water systems. However, if you require a specific liner or coating for drinking water, we can customize according to your standards. -
Q: How long is the lead time for a standard order?
A: For stock sizes (DN15-DN50), lead time is typically 7-10 working days. For larger sizes or custom configurations, please allow 15-25 working days depending on quantity. -
Q: Do you provide certificates from classification societies like CCS or DNV?
A: We can arrange third-party inspection and certification upon request. Additional costs and time will apply. The mill test report is included as standard. -
Q: What is the warranty coverage?
A: Our 12-month warranty covers manufacturing defects in materials and workmanship. It does not cover damage caused by improper installation, misuse, or wear and tear. We will replace or repair defective valves free of charge. -
Q: Can I get a sample before placing a bulk order?
