Documentation
Mill Test Report (MTR) supplied
As a professional manufacturer with ISO 9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance marine gate valves designed for demanding shipboard applications. Our valves are engineered to provide reliable shut-off in seawater, ballast, bilge, and cooling systems, backed by comprehensive Mill Test Reports and a solid 12-month warranty. With years of experience serving global maritime markets, we understand the critical need for durability, corrosion resistance, and operational safety in marine environments.
Our marine gate valves are manufactured to meet stringent international standards, ensuring compatibility with various shipbuilding specifications. The inclusion of a Mill Test Report with each valve provides full traceability of materials, giving shipyards, ship owners, and marine equipment suppliers complete confidence in the product's quality and compliance. This commitment to documentation and quality control minimizes risk and simplifies the approval process for your projects.
Key Features & Technical Advantages:
- Superior Corrosion Resistance: Manufactured from premium bronze alloys and other marine-grade materials specifically selected to withstand prolonged exposure to seawater, preventing premature failure and reducing maintenance cycles.
- Robust Construction: Features a sturdy body design, reinforced stem, and precision-machined gate and seats to handle high-pressure differentials and frequent operation cycles typical in marine service.
- Reliable Sealing Performance: Utilizes advanced sealing technologies and materials to ensure bubble-tight shut-off, critical for system isolation and preventing seawater ingress or fluid loss.
- Easy Operation & Maintenance: Designed with ergonomic handwheels or optional gear operators for smooth actuation even under high pressure. The design allows for in-line maintenance or repair when necessary.
- Versatile Configurations: Available in a wide range of sizes, pressure ratings, and connection types (flanged, screwed, welded) to seamlessly integrate into new builds or retrofit existing piping systems on vessels.
- Full Material Traceability: Each valve is supplied with a Mill Test Report (MTR) detailing chemical composition, mechanical properties, and test results, providing the documentation required for class society approvals and quality audits.
The following table outlines common specifications for our standard marine gate valve series. Custom configurations are available to meet specific project requirements.

Frequently Asked Questions (FAQ):
-
Q: What is included in the Mill Test Report (MTR) supplied with the valve?
A: The MTR is a certified document from the material mill. It typically includes the heat/heat code number, chemical composition analysis, mechanical property test results (yield strength, tensile strength, elongation), and any supplementary tests performed, providing full traceability. -
Q: Are your marine gate valves suitable for seawater service?
A: Yes, they are specifically designed for seawater applications. We offer materials like bronze (C95800, C83600) and selected stainless steels (CF8M) known for their excellent resistance to seawater corrosion and biofouling. -
Q: Can these valves be used with actuators for remote operation?
A: Absolutely. Our gate valves can be configured with mounting pads for pneumatic, hydraulic, or electric actuators. This is a common customization for automated ballast, cooling, or firefighting systems onboard. -
Q: What standards do your valves conform to?
A> Our manufacturing process is ISO 9001 certified. Valve design and testing can follow common marine and industrial standards such as API, ISO, ASME, DIN, or specific classification society rules (ABS, DNV, etc.) upon request. -
Q: What does the 12-month warranty cover?
A: Our warranty covers defects in materials and workmanship under normal use and service conditions for a period of 12 months from the date of shipment. It assures you of our commitment to product quality. -
Q: Do you offer custom sizes or pressure ratings outside your standard range?
A: Yes, as a manufacturer, we have the capability to engineer and produce valves in non-standard sizes, higher pressure classes, or with special material combinations to meet unique project specifications. -
Q: How do you ensure packaging for overseas marine shipment to prevent corrosion?
A> We employ robust export packaging, including VCI (Vapor Corrosion Inhibitor) paper, desiccant bags, and waterproof wrapping, to protect the valves from salt air and humidity during ocean transit. -
Q: What are your main shipping ports and lead times?
A: We primarily ship from Shanghai, Guangzhou, Hong Kong, and Beijing. Lead times vary based on order quantity and specifications; standard products typically have shorter lead times compared to customized orders.
