Frequently Asked Questions (FAQ)

What does CB/T3191 standard mean for this valve?
CB/T3191 is a Chinese national standard specifically for marine valves. It defines requirements for design, materials, testing, and performance to ensure suitability for shipboard use, including corrosion resistance and pressure handling.
Can this valve be used with other fluids besides seawater?
Yes. While optimized for marine environments, the valve's material options (like stainless steel) make it suitable for various fluids including oil, gas, and chemicals, depending on the selected configuration.
What is included in the "technical documentation support"?
We provide comprehensive documents such as detailed drawings, material certificates, test reports, installation manuals, and maintenance guides. For OEM clients, customized documentation with your branding is available.
How does the 12-month warranty work?
The warranty covers defects in materials and workmanship for 12 months from delivery. Should any issue arise under normal use as per specifications, we will repair or replace the valve at our cost.
