FAQ – Frequently Asked Questions

Q: What is the difference between a globe check valve and a swing check valve?
A: A globe check valve uses a disc that moves linearly along the seat, offering tighter sealing and quieter operation compared to swing types. It is ideal for high-pressure marine applications where backflow prevention is critical.
Q: Is the valve suitable for seawater cooling systems?
A: Yes, when ordered with stainless steel or corrosion-resistant materials, our valve can handle seawater. We recommend CF8M (316 stainless steel) for best performance in marine environments.
Q: Do you provide the Mill Test Report for each valve?
A: Absolutely. Every valve is individually hydrostatically tested, and a Mill Test Report (including material certificates and test results) is included with the shipment.
Q: Can the valve be installed vertically?
A: Yes, our straight globe check valve is designed for both horizontal and vertical installation. However, for vertical upward flow, ensure the disc moves freely against gravity – we can provide guidance.
Q: What flange standards do you follow?
A: Standard flanges are according to GB/T 9113 (PN series). We can also customize to ANSI B16.5 Class 150/300 or DIN flanges upon request. Please mention your required standard when ordering.
Q: Is the 1-year warranty comprehensive?
A: The warranty covers manufacturing defects in materials and workmanship for 12 months from delivery date. It does not cover damage caused by improper use, corrosion due to incompatible media, or normal wear. Please refer to our warranty policy for details.
Q: What certifications does your company hold?
A: We are ISO9001:2015 certified. Additional certifications (e.g., CE, ABS, DNV) can be provided for specific orders, but please confirm availability with our sales team.
Q: Can I get a sample before bulk order?
A: Yes, sample orders are welcome. We can produce a sample valve in your required size and material for testing. Lead time for samples is typically 15-20 working days.
