Frequently Asked Questions (FAQ):

Q: What makes this gate valve suitable specifically for marine fuel oil service?
A: It is constructed from corrosion-resistant carbon steel with a protective epoxy coating to withstand salty, humid marine environments. Its design complies with marine standards for pressure and fire safety relevant to fuel handling.
Q: Can these valves be supplied with different end connections?
A: Yes. While flanged ends are standard per ANSI or DIN specifications, other connection types like butt-weld ends can be customized upon request to fit your specific piping system.
Q: What is the typical delivery time for an order of DN150 valves?
A: For standard specifications, we maintain inventory for common sizes. Delivery typically takes 15-30 days ex-works, depending on order quantity and final destination. Expedited options are available.
Q: Are these valves suitable for other fluids besides fuel oil?
A: While optimized for fuel oil, they can also be used for other non-aggressive liquids like seawater, lubricating oil, or ballast water within the specified temperature and pressure ratings. Material compatibility should be verified for specific media.
Q: Do you provide documentation and certifications with the valves?
A: Yes. Each shipment is accompanied by a material test report, certificate of conformity, and operational manual. Our factory holds ISO9001 certification, ensuring consistent quality control.
Q: Is on-site technical support or installation guidance available?
A: We provide detailed installation manuals and are available for remote technical consultation. For complex projects, on-site support from our engineers can be arranged, subject to prior agreement.
Q: What are the main maintenance requirements for this valve?
A: Maintenance is minimal. Periodic external inspection for coating integrity and occasional lubrication of the stem threads are recommended. The bolted bonnet allows for internal inspection and seat replacement if needed after long service.
Q: How do you ensure quality control during manufacturing?
A: Our ISO9001 system mandates strict quality checks at every stage: raw material inspection, machining, assembly, pressure testing (as per ISO 5208), and final coating. Each valve is hydrostatically tested before shipment.
