As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Marine Electric Regulating Butterfly Valve, engineered for precise flow control in demanding maritime environments. Since our establishment in 2016, we have dedicated ourselves to producing high-quality industrial valves, exporting to a wide range of global markets. This valve is designed to offer reliable performance, durability, and ease of integration for shipboard systems, offshore platforms, and other marine applications where accurate regulation of fluids is critical.
Core Features & Technical Advantages:
- Precise 4-20mA Signal Control: The valve is equipped with an electric actuator that accepts a standard 4-20mA analog input signal, allowing for seamless integration with existing marine control systems, PLCs, and DCS for highly accurate and automated flow regulation.
- Wide Size Compatibility: Available in a comprehensive size range from DN50 to DN1200, this valve can accommodate various pipeline diameters commonly found in marine cooling systems, ballast water management, fuel oil transfer, and other shipboard fluid handling processes.
- Robust PN16 Pressure Rating: Designed to withstand a nominal pressure of PN16, the valve ensures reliable operation under the typical pressure conditions encountered in marine piping networks, providing a safety margin for system stability.
- Marine-Grade Construction: Manufactured from materials suitable for marine service, such as corrosion-resistant cast iron, ductile iron, or stainless steel bodies with compatible seat materials (like EPDM, NBR, or PTFE), the valve resists saltwater corrosion and harsh environmental factors.
- Electric Actuator Benefits: The electric regulating actuator offers advantages like remote operation, precise positioning, fail-safe options (upon request), and minimal maintenance compared to pneumatic alternatives, which is crucial for space-constrained and automated marine vessels.
- Compact & Lightweight Design: Butterfly valves inherently feature a compact and lightweight structure compared to other valve types, making them easier to install and handle onboard ships, saving valuable space and weight.
- Bidirectional Sealing: The valve design typically provides effective sealing in both flow directions, enhancing its versatility and reliability in complex piping layouts.
- Easy Maintenance: The seat can often be replaced without removing the valve body from the pipeline, significantly reducing downtime and maintenance costs during vessel operations or dry-docking.

Frequently Asked Questions (FAQ):
-
Q: What is the primary advantage of using a 4-20mA signal with this valve?
A: The 4-20mA analog signal is an industry-standard for process control. It allows for precise, continuous positioning of the valve disc (from 0-100% open) based on the signal value, enabling fine-tuned flow regulation. It is also highly resistant to electrical noise over long cable runs typical in shipboard installations. -
Q: Can this valve be used for seawater applications?
A: Yes, absolutely. For seawater service, we recommend selecting a body material like stainless steel (AISI 316/316L) and a compatible seat material such as EPDM or PTFE to ensure maximum corrosion resistance and longevity. -
Q: Is the electric actuator suitable for hazardous areas on ships?
A: Standard actuators may not be certified for hazardous zones. However, we can provide actuators with appropriate explosion-proof (Ex d, Ex e) certifications upon request, subject to your specific classification requirements (e.g., Zone 1, Zone 2). -
Q: What is the typical delivery time for an order?
A: Delivery time depends on the valve size, material specifications, and order quantity. For standard configurations in common sizes, lead times are generally competitive. We provide accurate delivery estimates upon receipt of your detailed inquiry. -
Q: Do you offer manual override on the electric actuator?
A: Yes, most of our electric actuators come equipped with a manual handwheel or crank for emergency operation or maintenance in case of power loss, which is a crucial feature for marine safety. -
Q: Can the valve be customized for different flange standards (e.g., ANSI, JIS)?
A: Yes, customization is available. While PN flanges are standard, we can manufacture valves with ANSI Class 150 flanges, JIS 10K flanges, or other standards to match your existing shipboard piping. -
Q: What after-sales support do you provide?
A: We offer comprehensive technical documentation, installation manuals, and responsive customer support. Spare parts, such as seals and seats, are readily available to minimize downtime. -
Q: Are there any special installation considerations for marine use?
A> It is recommended to install the valve with sufficient access space for the actuator and future maintenance. Proper support for the pipeline on both sides of the valve should be provided to avoid stress on the valve body, especially important in vessels subject to movement and vibration.
