As a leading manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve is proud to introduce our high-performance Marine Butterfly Valve. Engineered specifically for the demanding environments of shipbuilding and offshore applications, this valve combines robust construction with critical fire-safe technology. Our years of expertise in serving global maritime markets ensure that this product delivers the reliability and safety required for vital fluid control systems on vessels and marine platforms.
This valve is not just a component; it's a safeguard. Its fire-safe design, compliant with stringent industry standards, provides an essential layer of protection in high-risk scenarios. With an annual export value reflecting our international reach and trust from clients across North America, South America, Europe, Asia, Africa, and Oceania, we understand the diverse requirements of the global marine industry. Our valve is built to perform under pressure, resist corrosive elements, and ensure long-term operational integrity.
Core Product Features & Technical Advantages:
- Advanced Fire-Safe Design: Incorporates a specially engineered metal seat and sealing system that maintains a tight seal even under direct fire exposure, preventing catastrophic fluid release. The design principles adhere to API 607/6FA fire-test requirements.
- Full API 609 Compliance: Manufactured in strict accordance with API Standard 609 for butterfly valves, ensuring dimensional interchangeability, material integrity, and performance reliability expected in oil, gas, and marine services.
- Superior Corrosion Resistance: Available in a range of materials including stainless steel (316/316L), duplex steel, and coated carbon steel to withstand seawater, bilge water, ballast systems, and aggressive cargoes.
- Bubble-Tight Shutoff: Features a precision-machined disc and resilient or metal seat to achieve excellent sealing performance, minimizing leakage and ensuring efficient system isolation.
- Low Torque & Easy Operation: The streamlined disc design and high-quality bearing system reduce operating torque, allowing for smooth actuation with manual levers, gear operators, or automated actuators (pneumatic/electric).
- Compact & Lightweight Construction: The wafer or lug design offers significant space and weight savings compared to other valve types, a critical advantage in space-constrained shipboard installations.
- Versatile Actuation Options: Can be supplied as a manual valve or seamlessly integrated with a wide range of actuators for remote control and automation, supporting modern ship management systems.
- Extended Service Life: Robust stem sealing with multiple sealing points and anti-blowout stem design prevent failure and extend maintenance intervals, reducing total cost of ownership.

Frequently Asked Questions (FAQ):
-
Q: What exactly does "Fire-Safe Design" mean for this butterfly valve?
A: It means the valve is designed to maintain sealing integrity during and after exposure to fire. It typically incorporates a secondary metal seat that engages if the primary soft seal is compromised by heat, preventing uncontrolled fluid release. -
Q: Is this valve suitable for seawater applications?
A: Yes, absolutely. We recommend selecting body and trim materials like 316 Stainless Steel or Duplex Steel, which offer high resistance to chloride-induced corrosion from seawater in ballast, cooling, or service lines. -
Q: Can this valve be automated for remote operation?
A: Yes. The valve is designed for easy integration with pneumatic (double-acting or spring-return) or electric actuators. We can supply the complete assembly ready for installation. -
Q: What is the significance of API 609 compliance?
A: API 609 is a key standard for butterfly valves in the petroleum and natural gas industries. Compliance ensures the valve meets rigorous requirements for design, materials, testing, and dimensions, guaranteeing performance and interchangeability. -
Q: Do you provide certificates for the materials and fire-safe testing?
A> We provide material test certificates (MTC) for all critical components. While we design to fire-safe standards (API 607/6FA), specific fire-test certificates for a valve batch are available upon request and may involve additional testing. -
Q: What is the typical delivery time for an order?
A: Delivery time depends on the valve size, material, and quantity. Standard configurations typically have shorter lead times. We leverage our efficient supply chain and multiple export ports to provide accurate timelines with every quote. -
Q: Are special coatings or painting available for extra corrosion protection?
A: Yes. Standard epoxy coating is common. We also offer customizable coatings like high-build epoxy, zinc plating, or specialized marine paints to meet specific project specifications. -
Q: How do I select between Wafer and Lug end connections?
A: Wafer valves are sandwiched between flanges and are lighter/lower cost. Lug valves have threaded inserts allowing them to be bolted directly to a flange without a mating flange, useful for end-of-line service or where pipeline disassembly is needed. We can advise based on your piping layout.
