As a professional manufacturer specializing in industrial valves, Shanghai Zhibang Valve Manufacture Co., Ltd. brings you a robust and reliable solution for demanding marine applications. Our Marine Butterfly Valve, engineered to DIN 3202 standard, is specifically designed to handle the corrosive challenges of seawater systems. With critical components crafted from 316L stainless steel and an EPDM lining, this PN10, DN100 valve offers exceptional durability and leak-tight performance, making it an ideal choice for shipbuilding, offshore platforms, and coastal installations where reliability is non-negotiable.

This valve is built to withstand the harsh marine environment. The selection of materials is paramount for longevity in seawater service. The body and disc are constructed from 316L stainless steel, known for its superior resistance to pitting and crevice corrosion compared to standard 316 grades, especially in chloride-rich environments like seawater. The EPDM (Ethylene Propylene Diene Monomer) seat lining provides excellent sealing and outstanding resistance to ozone, weathering, and a wide range of chemicals commonly found in marine systems.

Key Technical Specifications and Advantages:

Superior Corrosion Resistance: The 316L stainless steel construction ensures long service life even in highly corrosive seawater, reducing maintenance frequency and replacement costs.
Reliable Sealing: The EPDM liner offers a bubble-tight seal, preventing leakage and ensuring system integrity. Its flexibility accommodates minor pipe misalignments.
Standard Compliance: Manufactured to DIN 3202 F1 series standard, ensuring dimensional interchangeability and compatibility with international piping systems.
Approved for Marine Use: The valve carries CCS (China Classification Society) approval, a critical certification for marine and offshore equipment, assuring quality and safety standards.
Low Operating Torque: The streamlined disc design and low-friction EPDM seat result in lower operating torque, allowing for easier manual operation or smaller actuator sizing.
Bi-Directional Flow: Suitable for flow in either direction, simplifying installation and system design.
Compact and Lightweight: The wafer-style design (typical for this standard) provides a space-saving and weight-saving solution compared to other valve types, crucial for marine weight budgets.

Frequently Asked Questions (FAQ):

Q: What is the main advantage of using 316L over standard 316 stainless steel for the disc?
A: 316L has a lower maximum carbon content, which significantly enhances its resistance to sensitization and subsequent intergranular corrosion, especially after welding or exposure to high temperatures. This makes it more suitable for the harsh, chloride-laden seawater environment.
Q: Is this valve suitable for both fresh and seawater applications?
A: While its construction is optimized for corrosive seawater, it performs excellently in freshwater, cooling water, and other mild chemical services. The 316L/EPDM combination offers broad chemical compatibility.
Q: Can this valve be fitted with an actuator for remote operation?
A: Yes. The valve is designed to be compatible with various pneumatic or electric actuators. The standard manual lever can be removed, and an actuator mounting kit can be supplied upon request.
Q: What does "CCS Approved" mean, and why is it important?
A: CCS (China Classification Society) approval indicates that the valve has been tested and certified by this recognized marine classification society to meet specific standards for materials, design, and manufacturing quality required for use on classified ships and offshore installations. It is often a mandatory requirement for marine projects.
Q: What is the expected service life of the EPDM lining in seawater?
A: Under normal operating conditions within the specified temperature and pressure range, the EPDM lining can provide reliable service for many years. Its lifespan depends on factors like cycle frequency, presence of abrasives, and exact water chemistry, but it is known for its excellent aging characteristics.
Q: Are other seat materials available besides EPDM?
A: Yes. While EPDM is standard for this seawater model, we can offer other elastomers like Viton (FKM) for higher temperature or different chemical services, and PTFE for wider chemical resistance, subject to customization.
Q: What is the difference between a wafer and a lug-style butterfly valve, and which is this?
A: This valve is typically supplied as a wafer type per DIN 3202. Wafer valves are installed between two pipe flanges, with bolts running through both flanges and the valve. Lug-style valves have threaded inserts (lugs) allowing them to be bolted directly to each flange, enabling isolation. The wafer design is more common for this standard and application.
Q: Do you provide documentation like material certificates and test reports?
A: Yes. As an ISO9001 certified manufacturer, we can provide standard documentation including material test certificates (MTC) and factory test reports for pressure testing, which are commonly required for marine projects.
