Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, specializes in the production of high-performance industrial valves for demanding global markets. Our DIN 3202 Marine Butterfly Valve is engineered to meet the rigorous standards of marine and offshore applications, where reliability and safety are paramount. As a manufacturer with ISO9001-certified quality management systems, we integrate full material traceability into every valve we produce, ensuring that each component's origin and quality are documented and verifiable. This commitment to transparency and quality control provides our clients, particularly in sectors like shipbuilding, oil & gas, and power generation, with unparalleled confidence in the durability and performance of our products.
Our butterfly valves are designed for efficient flow control in pipelines. The key features and technical specifications are detailed below:
- Compliance with DIN 3202 Standard: This ensures dimensional accuracy, flange connection compatibility, and performance metrics that are widely recognized and trusted in European and international engineering projects.
-
Robust Construction for Marine Environments: Materials are selected to resist corrosion from seawater, high humidity, and variable temperatures. Common material options include:
- Carbon Steel with protective coatings
- Stainless Steel (304, 316)
- Duplex/Super Duplex Stainless Steel for highly corrosive conditions
-
Full Material Traceability System: From raw material procurement to final assembly, every step is logged. This system allows for:
- Verification of material certificates (mill test reports).
- Tracking of batch numbers and heat codes.
- Providing auditable documentation for quality assurance and regulatory compliance.
-
Versatile Operation and Sealing: The valves can be operated manually via a handwheel or lever, or automated with gearboxes or pneumatic/electric actuators. The disc seal is critical for tight shut-off.
Sealing Material Typical Application Temperature Range PTFE (Polytetrafluoroethylene) General purpose, chemical resistance -20°C to +200°C EPDM (Ethylene Propylene Diene Monomer) Water, steam, mild chemicals -40°C to +150°C Metal Seat (Stainless Steel) High temperature, abrasive media Up to +500°C -

Frequently Asked Questions (FAQ)
-
Q: What does "Full Material Traceability" mean for this butterfly valve?
A: It means we maintain and can provide a complete documented record for every major component (body, disc, seal, stem) used in the valve. This includes material grade certificates, mill test reports, batch numbers, and our internal processing logs. This ensures quality and origin are verifiable. -
Q: Is the DIN 3202 standard compatible with ANSI or other flange standards?
A: DIN 3202 specifies dimensions for face-to-face length and flange connections primarily for the PN pressure rating system. While dimensional differences exist, adaptors or custom machining can be arranged. We can discuss compatibility with ANSI, JIS, or other standards based on your project requirements. -
Q: What are the typical applications for this marine butterfly valve beyond shipbuilding?
A: While designed for marine environments (ballast systems, cooling water, fuel lines), its robust construction and traceability make it suitable for offshore platforms, coastal power plants, chemical processing with corrosive media, and water treatment facilities requiring high reliability. -
Q: Can this valve be supplied with actuators for automated control?
A: Yes. The valve design accommodates the mounting of pneumatic (air), electric, or hydraulic actuators. We can supply the valve as a manual unit or as a complete package with an actuator and controls, customized to your signal requirements (on/off, modulating). -
Q: What material options are available for the body and disc to handle seawater corrosion?
A: For standard seawater applications, Stainless Steel 316/316L is commonly used. For more aggressive environments (high chloride, high temperature), Duplex Stainless Steel (2205) or Super Duplex (2507) are recommended options. Carbon steel with suitable epoxy or other protective coatings is also an option for certain services. -
Q: How does the traceability system help with maintenance and spare parts identification?
A: The traceability documentation includes material specifications and part identifiers. If a component needs replacement years later, this documentation helps in sourcing the correct material grade and compatible spare parts, ensuring system integrity is maintained. -
Q: What is the delivery lead time for these valves?
A: Lead time depends on size, material, and configuration. Standard sizes in common materials (e.g., DN150 316 Stainless Steel) may have shorter lead times. For custom sizes, special materials, or actuator packages, lead times will be longer. We provide estimated lead times upon receipt of detailed specifications. -
Q: Do you provide testing certificates for the valves?
A: Yes. Each valve undergoes pressure tests (shell and seat tests). Test reports/certificates can be provided upon request. For projects requiring third-party inspection or specific test standards, arrangements can be made.
