Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, is a dedicated manufacturer specializing in high-performance fluid control solutions for demanding industries. Our Marine Ball Valve represents our commitment to reliability and durability in harsh maritime environments. Designed with precision engineering and backed by an extended warranty and a comprehensive Mill Test Report, this product offers shipbuilders, offshore operators, and marine system integrators a trusted component for critical applications, ensuring long-term operational safety and cost-effectiveness.
Our valves are engineered to meet the rigorous demands of marine service. Key features and advantages include:
- Robust Construction: Manufactured from high-grade materials such as carbon steel, stainless steel, or specialized alloys, selected for corrosion resistance and strength against seawater and marine atmospheres.
- Precision Sealing: Utilizes advanced sealing materials like PTFE or reinforced composites to ensure leak-free operation even under high pressure and variable temperature conditions common in marine systems.
- Versatile Actuation: Available in manual, pneumatic, or electric actuation options, providing flexibility for integration into automated control systems or for manual override requirements.
- Extended Warranty Coverage: We provide an extended warranty period beyond standard offerings, reflecting our confidence in the product's quality and durability, reducing long-term maintenance costs for clients.
- Full Documentation: Each valve is accompanied by a comprehensive Mill Test Report (MTR), detailing material composition, mechanical properties, and test results, providing full traceability and quality assurance for regulatory compliance and project documentation.
- Global Compliance: Our manufacturing process is certified under the ISO9001 quality management system, ensuring consistent production standards suitable for international projects.

Frequently Asked Questions (FAQ)
Q1: What exactly is included in the "Comprehensive Mill Test Report"?
A: The Mill Test Report is a detailed document provided with each valve. It typically includes certified information on the raw material's chemical composition, mechanical properties (like tensile strength, hardness), heat treatment records, and non-destructive test results (if applicable). This serves as material traceability and quality proof for your project documentation.
Q2: How long is the "Extended Warranty" period?
A: The specific warranty period duration is defined in our commercial terms and can vary based on the product model and application. It is typically longer than standard industry warranties for similar products. Please inquire for the exact warranty coverage for your selected valve configuration.
Q3: Are these valves suitable for seawater and offshore corrosive environments?
A: Yes, they are designed for marine applications. We offer materials like 316/316L stainless steel, duplex steels, and other corrosion-resistant alloys specifically to withstand seawater, salt spray, and offshore conditions. Material selection should be based on your specific service environment.
Q4: Can I get valves with pneumatic or electric actuators for remote operation?
A> Absolutely. While manual operation (lever or gear) is standard, we provide options for pneumatic (air-operated) and electric motor actuators. These can be sourced and mounted as per your requirements for integration into automated control systems.
Q5: What pressure classes are available beyond the standard rating?
A> Our valves can be manufactured to higher pressure ratings such as Class 300, Class 600, PN25, PN40, etc. The design (body thickness, seal type, etc.) will be adjusted accordingly. Please specify your required pressure class during inquiry.
Q6: Do you offer custom sizes or special end connections?
A> Yes, we support customization. While our standard range covers common sizes from DN15 to DN300 (and up to DN600), we can manufacture valves to specific dimensional requirements. Special end connections (like proprietary flange types or welding ends) can also be accommodated upon request.
Q7: How does the ISO9001 certification benefit me as a buyer?
A> Our ISO9001 certification ensures that our manufacturing processes are systematically controlled and consistently produce valves that meet defined quality standards. It provides confidence in the reliability and consistency of our products, which is crucial for critical marine applications.
Q8: What are the main shipping ports and typical delivery times?
A> We primarily ship from Shanghai, Guangzhou, Hongkong, and Beijing ports. Delivery times depend on order quantity, customization level, and destination. For standard products, we can often offer competitive lead times. Please contact us for a specific schedule based on your order.
