FAQ
-
Q: What does "CB/T3191" refer to in the product title?
A: CB/T3191 is a Chinese national standard specifically for marine valves. It outlines requirements for design, materials, testing, and performance for valves used on ships, ensuring they meet safety and operational criteria for marine environments. -
Q: Can this valve be used for other fluids besides freshwater and fuel oil?
A: While designed primarily for freshwater and fuel oil, its material and seal options (like stainless steel and PTFE) may suit other non-aggressive marine fluids. Please consult with us for specific fluid compatibility based on your application. -
Q: What is the advantage of a manual gear operation compared to a standard handwheel?
A: The gear mechanism provides a torque multiplication effect. It allows an operator to open or close the valve more easily, especially for larger sizes or under higher system pressures, reducing the required manual force. -
Q: Are these valves suitable for high-pressure fuel oil systems?
A: Yes, with pressure ratings up to PN25 (approximately 25 bar), they are capable of handling typical pressures found in shipboard fuel oil systems. Confirm your system's maximum pressure when selecting the valve. -
Q: What material option is best for seawater applications?
A: For applications involving seawater or highly corrosive environments, Stainless Steel 316 is generally recommended due to its superior corrosion resistance compared to bronze or carbon steel. -
Q: Do you offer customization for different connection standards or special sizes?
A: Yes, customization is available. We can provide valves with specific thread types (NPT, BSPT) or flange standards (ASME, DIN, JIS) upon request. Non-standard sizes may also be customizable. -
Q: What is the typical delivery time for orders?
A: Delivery time depends on order quantity and specific requirements. For standard sizes and materials, we maintain inventory for prompt shipment from our ports (Shanghai, Guangzhou, etc.). Lead times for customized orders will be communicated upon inquiry. -
Q: Does the valve come with any warranty or after-sales support?
A: Our products are backed by a quality guarantee consistent with our ISO9001 system. We provide technical support for installation and operation. Specific warranty terms can be discussed based on the order.
