As a leading manufacturer with ISO 9001 certification and a strong export presence across global marine markets, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our specialized High Temperature Butterfly Valve for Marine Service. Engineered to meet the rigorous demands of shipboard environments, this valve is designed for reliability in high-temperature applications such as engine exhaust systems, cargo handling, and auxiliary machinery. Our commitment to quality, backed by nearly a decade of manufacturing expertise since 2016, ensures a product that delivers exceptional performance and longevity, helping vessel operators and shipyards maintain operational efficiency and safety compliance.
This valve series is the result of extensive research and development, focusing on the unique challenges faced in marine engineering. The core design prioritizes durability under thermal stress and corrosion resistance in saline atmospheres. We utilize advanced materials and precision machining to create a valve that not only meets but often exceeds the expectations of shipbuilders, repair yards, and equipment suppliers worldwide. Our annual export volume of US$1-1.5 million to key regions including North America, Europe, and Southeast Asia is a testament to the trust placed in our products by the international maritime community.
Key Product Features & Technical Advantages:
- Superior High-Temperature Performance: The valve is constructed with specially selected alloys and heat-treated components capable of withstanding continuous service temperatures up to 650°C (1202°F). This makes it ideal for critical high-heat zones on vessels.
- Robust DNV Compliance: Manufactured in strict accordance with DNV (Det Norske Veritas) standards for marine applications, ensuring acceptance in international shipbuilding and classification society approvals.
- Advanced Sealing Solutions: Offers a choice between resilient soft seats (PTFE) for tight shut-off in moderate temperatures and durable metal seats for extreme high-temperature and abrasive service, minimizing leakage and maintenance.
- Corrosion-Focused Design: All wetted parts are made from marine-grade stainless steel (e.g., 316, 316L) or coated carbon steel, providing excellent resistance to saltwater, humid air, and chemical exposure common in marine environments.
- Versatile Actuation & Control: Available with manual gear operators for simple applications, or can be seamlessly fitted with pneumatic or electric actuators for remote and automated process control integration.
- Compact & Lightweight Construction: The butterfly valve design offers a significant space and weight saving compared to gate or globe valves, a critical factor in ship design where every kilogram and cubic meter counts.

Frequently Asked Questions (FAQ):
-
Q: What specific DNV standards does this valve comply with?
A: The valve is designed and manufactured to meet the relevant DNV rules for marine and offshore applications, particularly those covering materials, design, pressure testing, and fire safety for valves used in ship systems. Exact rule references (e.g., DNVGL-RU-SHIP-Pt4Ch5) can be provided upon request for your classification society submission. -
Q: Can this valve be used for both freshwater and seawater cooling systems?
A: Yes, absolutely. The standard marine-grade materials like 316/316L stainless steel offer excellent corrosion resistance in both freshwater and seawater environments. For highly chlorinated or aggressive media, material upgrades are available. -
Q: What is the delivery lead time for a standard size order?
A: For standard sizes and materials from our inventory, lead time is typically 15-30 days. For large or customized orders, we provide a precise timeline upon receipt of your detailed specifications. We ship efficiently from major ports like Shanghai and Hong Kong. -
Q: Do you provide valves with actuators, and are they also marine-certified?
A: Yes, we offer complete packages with pneumatic, electric, or hydraulic actuators. The actuators can be sourced to meet marine requirements such as IP67/IP68 ingress protection, corrosion-resistant coatings, and relevant type approvals, ensuring a fully compliant solution. -
Q: How does the metal seat perform compared to a soft seat in high-temperature service?
A: The metal seat is specifically designed for temperatures exceeding the limits of polymers (above ~250°C). It provides durable, long-lasting sealing in extreme heat but may have a slightly higher permissible leakage rate compared to a soft seat at lower temperatures. The choice depends on your specific temperature and tightness requirements. -
Q: Is this valve suitable for emergency shutdown (ESD) service on ships?
A: When paired with a suitable fail-safe actuator (spring-return pneumatic or electric), this butterfly valve can be configured for ESD or fire-safe applications. We can design the package to meet specific safety integrity level (SIL) or fire-testing requirements as needed. -
Q: What kind of testing is performed before shipment?
A> Every valve undergoes rigorous testing, including shell and seat pressure tests (per API 598/ISO 5208), operational torque testing, and material verification. Certified test reports are provided with the shipment. -
Q: Can you customize the valve face-to-face dimensions or flange standards?
A: Yes, customization is a core part of our service. We can adjust dimensions to fit existing piping or manufacture to various international flange standards (ANSI, JIS, DIN, GOST, etc.) based on your project specifications.
