As a professional manufacturer specializing in industrial valves since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Electric Actuated Butterfly Valve designed specifically for demanding marine environments. This valve combines the robust corrosion resistance of an Aluminum Bronze disc with precise electric actuation and a standardized 4-20mA control signal, offering shipbuilders, offshore operators, and marine system integrators a reliable and efficient solution for fluid control. Engineered to withstand the harsh conditions of seawater, humidity, and variable pressures, it delivers superior performance for ballast systems, cooling circuits, fuel lines, and general service applications onboard vessels and offshore platforms.
Core Product Features & Technical Advantages:
- Marine-Grade Material Construction: The disc is crafted from Aluminum Bronze, a copper alloy renowned for its exceptional resistance to seawater corrosion, biofouling, and erosion. This material choice significantly extends service life compared to standard materials in saline environments.
- Precision Electric Actuation: The valve is equipped with an electric actuator that accepts a standard 4-20mA control signal, enabling seamless integration with modern ship automation systems, PLCs, and control panels for remote or automated operation.
- Robust Design for Marine Service: The valve body, typically available in cast iron, cast steel, or ductile iron, is designed with marine considerations, featuring coatings or treatments to enhance corrosion protection.
- Flexible Configuration: Available in both On/Off (two-position) and modulating (proportional control) versions, allowing for simple shut-off or precise flow rate adjustment based on system requirements.
- Compact & Space-Efficient: The butterfly valve design offers a compact profile compared to other valve types, which is crucial in space-constrained marine engineering applications.
- Easy Maintenance & Operation: Designed for reliability with features like a manual override handwheel (optional) for emergency operation, visual position indicators, and accessible sealing components.

Frequently Asked Questions (FAQ):
-
Q: Why is Aluminum Bronze specifically chosen for the disc in a marine valve?
A: Aluminum Bronze (CuAl) offers superior resistance to corrosion in seawater, including resistance to dezincification and biofouling. It maintains its mechanical properties in saline environments, making it a preferred material for critical marine valve components to ensure long service life. -
Q: Can this valve be used for both freshwater and seawater systems on a vessel?
A: Yes, absolutely. While its Aluminum Bronze disc is particularly advantageous for seawater applications due to corrosion resistance, the valve is fully suitable for freshwater systems, cooling water, fuel, and other onboard fluids. The material selection provides versatility. -
Q: What does "4-20mA control signal" mean for installation and operation?
A: 4-20mA is a standard analog signal in industrial automation. It means the valve's electric actuator receives a control current between 4 milliamps (typically representing "closed" or 0% open) and 20 milliamps ("fully open" or 100%). This allows precise proportional control if a modulating actuator is used, and easy wiring to standard PLCs or control systems. -
Q: Is a manual operation option available if the electric actuator fails or power is lost?
A: Yes, an optional manual override feature is available. This usually involves a handwheel or lever attached to the actuator that allows personnel to operate the valve manually in emergency situations or for maintenance, ensuring system safety and continuity. -
Q: How do I select the correct valve size (DN) for my pipeline?
A: The valve size (DN) should match the nominal diameter of your pipeline. Our standard range covers DN50 to DN600. You should provide your pipeline's nominal diameter and flange standards (e.g., ANSI, DIN, JIS) for us to supply the correctly sized valve. -
Q: Are these valves suitable for high-pressure marine applications?
A: Our standard pressure ratings are PN10 and PN16, which cover many marine service applications. For higher pressure requirements (e.g., certain hydraulic systems), we can customize the valve design, including body material and sealing, upon request. Please specify your required pressure class. -
Q: What is the typical lead time for orders, and from where are they shipped?
A: Lead times vary based on order quantity and specifications. As an established manufacturer with an annual export volume of US$1-1.5 Million, we maintain efficient production planning. We ship from major Chinese ports including Shanghai, Guangzhou, Hong Kong, and Beijing, facilitating logistics to global destinations. -
Q: Does the valve come with any position feedback to the control system?
A: Yes, this is an available optional feature. We can provide actuators with a 4-20mA output signal or other feedback signals (e.g., potentiometer, switch) that indicate the valve's real-time position (open percentage) to the control system, enabling monitoring and closed-loop control.
