As a leading manufacturer with a strong global presence, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance DIN 3202 Stainless Steel Butterfly Valve, engineered specifically for the demanding environments of marine ballast water systems. With our ISO9001-certified production processes and a track record of exporting to major markets worldwide, we deliver valves that combine robust construction, reliable sealing, and exceptional corrosion resistance. This valve is designed to meet the stringent requirements of shipbuilding and offshore applications, ensuring safe and efficient control of ballast water flow.
Our valve is built to provide long-lasting service in corrosive seawater environments. Key features and specifications include:
- Superior Corrosion Resistance: Manufactured from 316L stainless steel, offering enhanced protection against pitting and crevice corrosion in chloride-rich environments like seawater.
- Robust DIN Standard Design: Compliant with DIN 3202-F1 standards, ensuring dimensional accuracy, interchangeability, and reliable performance under PN16 pressure.
- Versatile Size Range: Available in nominal diameters from DN50 (2") to DN300 (12"), catering to various pipeline requirements in ballast systems.
- Bubble-Tight Sealing: Features a precision-machined disc and a resilient seat (options include EPDM, PTFE, or NBR) to achieve excellent shut-off, minimizing leakage.
- Low Torque Operation: The streamlined disc design and high-quality bearings reduce operating torque, allowing for smoother actuation and smaller actuator requirements.
- Compact & Lightweight: The wafer or lug design provides a space-saving and weight-efficient solution compared to other valve types, crucial for marine applications.
- Bi-Directional Flow Capability: Suitable for flow in both directions, simplifying installation and system design.

Frequently Asked Questions (FAQ):
-
Q: Is this valve suitable for seawater applications?
A: Yes, absolutely. The use of 316L stainless steel provides superior resistance to corrosion from chlorides in seawater, making it an ideal choice for ballast water systems. -
Q: What is the difference between a wafer and lug style valve?
A: A wafer valve is installed between two flanges using bolts that pass through both flanges. A lug-style valve has threaded inserts (lugs) on both sides, allowing it to be installed using bolts only on one side, which can be beneficial for end-of-line applications or easier maintenance. Both types are available. -
Q: Can this valve be used with other fluids besides seawater?
A: While designed for marine service, its 316L construction and available seal options (EPDM, PTFE, NBR) make it suitable for a range of corrosive or clean fluids in chemical, pharmaceutical, and food processing industries, depending on temperature and media compatibility. -
Q: What actuation options are available?
A: We supply the valve as a manual unit (lever or gear operator) or prepared for the installation of automated actuators. Electric, pneumatic, and hydraulic actuators can be sourced and fitted based on your system requirements. -
Q: What is the lead time for an order of DN200 valves?
A: Lead times vary based on order quantity and specific configuration (seat material, actuation). Standard items typically have shorter lead times. Please contact our sales team with your detailed requirements for an accurate timeline. -
Q: Do you provide documentation like test reports or material certificates?
A: Yes, as an ISO9001-certified manufacturer, we can provide standard documentation including material test reports. Specific certification requirements can be discussed during the order process. -
Q: Is the valve pressure rating suitable for high-pressure ballast pumps?
A: The PN16 rating (16 bar at 20°C) is suitable for many standard ballast system pressures. For higher pressure requirements, please inquire about other pressure class options we may have available. -
Q: How do I determine the right seat material (EPDM, PTFE, NBR) for my application?
A: The choice depends on the fluid temperature, chemical compatibility, and required sealing performance. EPDM is a common, versatile elastomer. PTFE offers excellent chemical resistance. NBR is good for oils. Our technical team can assist you in selecting the most appropriate material.
