As a leading manufacturer with a strong foundation since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance industrial valves for global markets. Our DIN 3202 Marine Butterfly Valve in 316 Stainless Steel is engineered specifically for demanding OEM applications in marine environments. This valve represents our commitment to delivering robust, corrosion-resistant, and reliable flow control solutions that meet stringent international standards, ensuring seamless integration into your systems and long-term operational integrity.
Crafted from premium 316 stainless steel, this butterfly valve offers exceptional resistance to pitting and crevice corrosion caused by chlorides, making it an ideal choice for seawater, ballast, cooling, and bilge systems. The design conforms to DIN 3202 specifications, ensuring compatibility with European piping systems and providing a reliable seal under various pressure conditions. Its compact, lightweight construction allows for easy installation and maintenance, even in space-constrained engine rooms or onboard piping networks.
Key Features and Technical Advantages:
- Superior Corrosion Resistance: The use of 316 stainless steel, with added molybdenum, provides enhanced protection against corrosive marine atmospheres and media, significantly extending service life.
- DIN Standard Compliance: Manufactured to DIN 3202 F1/F4/F5 standards, ensuring dimensional accuracy, reliable flange connections, and interchangeability within European-designed systems.
- Versatile Sealing Options: Available with various seat materials like PTFE for wide chemical compatibility, EPDM for freshwater, or Viton for high-temperature and hydrocarbon service, allowing customization for specific fluid media.
- Low Torque Operation: The precision-engineered disc and seat design minimize operating torque, enabling smooth actuation with manual levers, gear operators, or automated actuators.
- Bidirectional Sealing: Provides effective shut-off in both flow directions, a critical feature for many marine applications where flow reversal can occur.
- Minimal Pressure Drop: The streamlined disc design offers low flow resistance when fully open, optimizing system efficiency and reducing pumping energy costs.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of 316 stainless steel over 304 for marine valves?
A: 316 stainless steel contains molybdenum (2-3%), which significantly increases its resistance to chloride-induced corrosion, such as pitting and crevice corrosion commonly encountered in seawater and marine atmospheres. This makes it a more suitable and durable choice for marine applications compared to 304 stainless steel. -
Q: Can this DIN 3202 valve be used with ANSI/ASME flanges?
A: While designed for DIN flange dimensions, our valves can often be adapted. It's crucial to check pressure ratings and bolt hole patterns. We recommend consulting our engineering team for specific compatibility requirements or inquiring about valves built to ANSI standards if needed. -
Q: What types of actuation can be fitted to this butterfly valve?
A: The valve is designed to accommodate a wide range of actuators. Standard options include manual lever handles and worm gear operators. For automated control, we can fit pneumatic (double-acting or spring-return) or electric actuators (on/off or modulating). The specific model and mounting interface can be customized. -
Q: Is the valve suitable for potable water or aggressive chemicals onboard?
A: Yes, with the appropriate seat material selection. For potable water, EPDM seats are commonly used. For aggressive chemicals, PTFE or Viton seats offer wider chemical resistance. The 316 stainless steel body provides excellent compatibility with many media. -
Q: What is the typical lead time for OEM orders?
A: Lead time depends on order quantity, customization level, and valve size. For standard configurations in moderate volumes, production typically takes 4-6 weeks. We provide more accurate timelines upon receipt of your detailed specifications. -
Q: Do you provide documentation like material certificates and test reports?
A: Yes, as part of our ISO9001 commitment, we can provide material test certificates (MTC) for the stainless steel and other components. Functional test reports (e.g., shell test, seat test) are also available upon request to support your quality assurance processes. -
Q: Can you customize the valve with special markings, packaging, or paint?
A: Absolutely. As an OEM partner, we offer customization such as specific nameplate markings, company logos, special packaging for bulk shipment, and even specific paint colors if required for your project identification. -
Q: What is your payment terms for first-time OEM clients?
A: Standard terms are T/T (Telegraphic Transfer), with a common structure being 30% deposit with order and 70% balance before shipment. We are open to discussing terms based on order value and established business relationships.
