As a leading valve manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance Cast Steel Body Marine Butterfly Valve. Engineered specifically for demanding marine and petrochemical piping applications, this gearbox-operated valve combines robust construction with precise control. Since our establishment in 2016, we have dedicated ourselves to producing industrial valves that meet the rigorous standards of global markets, from North America and Europe to Southeast Asia and Africa. Our valve is designed to offer a dependable, long-lasting solution for fluid control in critical systems, ensuring operational safety and efficiency for our clients worldwide.

This marine-grade butterfly valve is built to withstand the harsh conditions of offshore platforms, shipboard piping, and petrochemical processing plants. Its core design focuses on durability, ease of operation, and maintenance, making it a preferred choice for engineers and procurement specialists. We understand that in industries where downtime is costly, reliability is paramount. Therefore, every valve undergoes stringent quality checks in our ISO9001-certified facility before shipment from major ports like Shanghai, Guangzhou, or Hong Kong.

Key Product Features & Technical Advantages:

Robust Cast Steel Construction: The valve body is manufactured from high-grade cast steel, providing exceptional strength and resistance to corrosion, which is crucial for marine environments with high salinity and petrochemical services involving corrosive media.
Efficient Gearbox Operation: The integrated gearbox operator allows for smooth and effortless opening and closing, even under high differential pressures. It reduces the required manual torque significantly, enhancing operator safety and enabling the use of the valve in larger sizes where handwheel operation would be impractical.
Superior Sealing Performance: Available with a variety of seat materials such as PTFE for general purposes, EPDM for wider temperature ranges, or metal seats for high-temperature applications. This ensures a bubble-tight seal and minimal leakage, meeting stringent industry standards.
Versatile Design & Application: Designed in compliance with international standards like API 609 and ISO 5752, this valve is suitable for a broad spectrum of services including cooling water, ballast systems, fuel oil, cargo handling, and various process fluids in petrochemical plants.
Low Maintenance & Long Service Life: The simple yet sturdy design minimizes wear parts. The gearbox is sealed and lubricated for life under normal conditions, and the disc/stem assembly is designed for easy replacement if needed, reducing long-term ownership costs.
Customization Options: We offer flexibility to meet specific project requirements. Customers can request variations in trim materials, pressure ratings, end connections (wafer or lug), and actuation options (pneumatic or electric actuators available upon request).

Frequently Asked Questions (FAQ):

Q: What makes this valve suitable for "marine" applications?
A: The term "marine" refers to its design and material selection to resist corrosion from saltwater, humidity, and harsh offshore conditions. The use of cast steel body, corrosion-resistant trim like stainless steel, and specific protective coatings (available upon request) make it ideal for ships, oil rigs, and coastal plants.
Q: Can this valve be used for onshore petrochemical plants as well?
A: Absolutely. While designed for marine durability, its cast steel construction and compliance with API 609 make it equally suitable for onshore petrochemical, refinery, power generation, and other industrial piping systems handling water, oil, gas, and mild chemicals.
Q: What is the advantage of a gearbox operator over a simple hand lever?
A: A gearbox provides a high gear ratio, multiplying the input torque. This allows an operator to open or close the valve against high pipeline pressures with significantly less effort, making it feasible and safe for larger valve sizes (typically above DN200).
Q: Are pneumatic or electric actuators available for this valve?
A: Yes. The valve is designed with a standard gearbox that can be easily fitted with various pneumatic (on/off or modulating) or electric actuators. Please specify your actuation requirements when inquiring.
Q: What pressure classes do you offer?
A: We commonly supply valves in PN10, PN16, PN25, and PN40 ratings (metric). Equivalent ASME Class 150 and Class 300 valves are also available. The specific pressure rating should be selected based on your system's design pressure.
Q: Do you provide certificates with the valves?
A: As an ISO9001-certified manufacturer, we provide a Material Test Report (MTR) or Certificate of Conformity (CoC) for the valves upon request. Other specific certifications can be discussed based on project needs.
Q: What is your typical delivery time?
A: Delivery time depends on the order quantity, size, and material specifications. Standard configurations typically have shorter lead times. We leverage our efficient production and multiple shipment ports to ensure prompt delivery.
Q: Can you customize the valve face-to-face dimensions?
A: Our standard valves comply with API 609/ISO 5752 face-to-face dimensions to ensure interchangeability. Non-standard dimensions can be considered for custom projects; please provide your detailed requirements for evaluation.
