Frequently Asked Questions (FAQ)
-
What is the main application of this marine drain valve?
It is designed for draining bilge water, seawater, tanks, and other non-corrosive fluids on ships, offshore platforms, and marine vessels. -
Can I choose between cast iron and steel?
Yes. Cast iron is suitable for standard drainage systems; steel is recommended for higher pressure or more corrosive environments. Both options are available. -
What does CCS certification mean?
CCS stands for China Classification Society. It indicates that the valve has been tested and approved for use in marine applications, meeting international safety and quality standards. -
Do you offer custom sizes beyond DN15-DN50?
While our standard range is DN15 to DN50, we can produce larger sizes (e.g., DN65, DN80) upon request with a minimum order quantity. Please contact our sales team for details. -
How is the valve installed?
Installation is straightforward: align the valve with the pipeline flanges or threads, tighten bolts or fitting, and ensure proper sealing. A manual handwheel allows easy open/close operation. -
What maintenance is required?
Regular inspection of the sealing surface and stem lubricant is recommended. The valve is designed for low maintenance, but periodic cleaning of deposits is advised. -
What is the typical lead time for orders?
Standard sizes (DN15-DN50) are usually shipped within 15-25 working days after confirmation. Custom orders may take longer. We ship from Shanghai, Guangzhou, or other ports. -
Can I get a sample before bulk order?
Yes, sample orders are welcome. We can provide a sample for evaluation; the sample cost will be deducted from the bulk order.
