As a specialized manufacturer with a strong focus on industrial valve solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our OEM Cast Iron DIN 3352 Marine Gate Valve. Engineered for demanding marine applications, this valve combines robust construction with reliable performance, making it an essential component for shipbuilding, offshore platforms, and port facilities. Our commitment to quality, backed by ISO9001 certification, ensures that every valve meets stringent standards for durability and safety in corrosive seawater environments. We understand the critical need for dependable flow control in marine systems, and our handwheel-operated gate valve is designed to deliver just that—sealing integrity and long service life under pressure.
The core value of this valve lies in its specialized design for marine use. Unlike standard valves, it is built to withstand the unique challenges posed by seawater, including high salinity, pressure fluctuations, and constant exposure to harsh elements. The handwheel operation provides precise manual control, which is often preferred for its simplicity and reliability in critical marine pipelines. With an annual export value reflecting our global reach across markets from North America to Southeast Asia, we have honed our expertise in delivering valves that perform consistently in diverse operating conditions.
Key Features and Technical Advantages:
- Superior Corrosion Resistance: The cast iron body is often treated with specialized coatings or finishes (e.g., epoxy coating) to enhance its resistance to seawater corrosion, extending the valve's lifespan significantly.
- Robust DIN 3352 Design: Compliance with the DIN 3352 standard ensures dimensional accuracy, interchangeability, and reliable performance under specified pressure ratings, facilitating easier installation and maintenance.
- Reliable Sealing Mechanism: Features a wedge gate or parallel gate design that provides a tight seal when closed, minimizing leakage and ensuring efficient flow isolation—a critical factor for safety and efficiency on vessels.
- Ergonomic Handwheel Operation: The handwheel is designed for easy manual control, even in tight or hard-to-reach spaces onboard ships. It allows for smooth opening and closing, reducing operator effort.
- Flanged Connection: Standard flanged ends (as per DIN standards) enable secure and leak-proof connections to piping systems, simplifying integration into existing marine infrastructure.
- Wide Pressure and Temperature Range: Suitable for various pressure classes (typically PN10/PN16) and temperatures up to 200°C, accommodating different fluid types and system requirements in marine environments.
- OEM Flexibility: As a manufacturer, we offer OEM services, allowing for customization in dimensions, coatings, markings, and packaging to meet specific client specifications or branding needs.

Frequently Asked Questions (FAQ):
-
Q: Is this cast iron valve suitable for full immersion in seawater?
A: While cast iron offers good general corrosion resistance, for prolonged full immersion, we recommend discussing optional specialized epoxy or other protective coatings to enhance longevity in such aggressive conditions. -
Q: Can the handwheel be replaced with a gearbox or actuator for remote operation?
A: Yes, the valve design can often be adapted. We offer optional gear operators or can provide valves prepared for actuator mounting (with an extended yoke) upon request for automated control systems. -
Q: Are the flanges compatible with ANSI standard piping?
A: While designed to DIN standards, we can supply valves with flanges machined to ANSI specifications (e.g., ANSI Class 150) to ensure compatibility with your existing North American or international piping. -
Q: What is the typical lead time for an OEM order of these valves?
A: Lead time varies based on order quantity and customization level. For standard sizes and specifications, production can typically be completed within 30-45 days after order confirmation. -
Q: Does the valve come with any warranty?
A: Yes, we provide a standard warranty against manufacturing defects. The specific warranty period and terms can be confirmed in our commercial agreement and are based on the application. -
Q: What fluids besides seawater can this valve handle?
A: This valve is suitable for a variety of fluids including fresh water, oil, gas, and other non-aggressive media within its specified pressure and temperature ratings. The seat material can be selected accordingly. -
Q: How do I determine the correct size (DN) for my application?
A: The valve size should match your pipeline's nominal diameter. Our technical team can assist you in selection based on your flow rate, pressure drop requirements, and system drawings. -
Q: Are testing certificates provided with the valves?
A: Standard production testing (like shell test, seat test) is conducted. Detailed test certificates can be provided as a deliverable, which is a common requirement for marine projects.
