Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of a dual plate check valve compared to a swing check valve in ballast water systems?
A: The dual plate design is more compact and lightweight, which reduces installation space and weight. It also offers faster closing response, reducing water hammer and protecting pumps and piping. -
Q: Is the valve suitable for both seawater and freshwater ballast systems?
A: Yes, the 316L stainless steel construction provides excellent corrosion resistance in both seawater and freshwater environments. Additional coating options are available upon request. -
Q: What certificates are included with the valve?
A: Each valve comes with LR and ABS type approval certificates as standard. We also provide ISO9001 factory certification and material test reports (MTR) if required. -
Q: Can the valve be supplied with flanges to other standards (e.g., ANSI, JIS)?
A: Yes, we can customize the end connections to ANSI B16.5, JIS B2238, or other standards. Please specify your requirements when ordering. -
Q: What is the typical lead time?
A: For standard sizes (DN50–DN200), lead time is approximately 15–25 working days. Larger sizes or custom orders may require 30–40 working days. -
Q: How do you ensure valve sealing performance?
A: Every valve is subjected to hydrostatic shell test (1.5x rated pressure) and seat leakage test (1.1x rated pressure) in accordance with API 598 standards. -
Q: Do you provide installation and maintenance manuals?
A: Yes, we supply a detailed installation, operation, and maintenance (IOM) manual with every shipment, along with drawings and warranty information. -
Q: What payment terms are available?
A: We accept T/T, L/C, and other negotiable terms. For first-time orders, a 30% deposit is typically required with 70% against shipping documents.
