As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable and high-performance fluid control solutions for the global maritime industry. Our Electric Actuated Marine Ball Valve, designed in strict compliance with the CB/T3191 standard and featuring a robust IP67 waterproof rating, represents our commitment to engineering excellence and operational safety in harsh marine environments. This valve is engineered to deliver precise control, exceptional durability, and minimal maintenance for critical piping systems on vessels and offshore platforms.

Core Features & Technical Advantages:

Superior Sealing & Corrosion Resistance: The valve body and ball are precision-machined from high-grade materials such as cast steel CF8M (316 stainless steel) or bronze, ensuring excellent resistance to seawater corrosion, erosion, and cavitation. Combined with reinforced PTFE or metal-seated seals, it guarantees zero leakage and long service life even under high-pressure cycling.
IP67 Waterproof Electric Actuator: The integrated electric actuator is fully encapsulated to achieve an IP67 rating, meaning it is completely protected against dust ingress and can withstand temporary immersion in water up to 1 meter for 30 minutes. This makes it ideal for deck applications, bilge systems, and other exposed or potentially flooded locations.
CB/T3191 Standard Compliance: The valve's design, material selection, manufacturing, and testing procedures strictly adhere to the Chinese CB/T3191 standard for ship valves. This ensures compatibility with international marine specifications, guaranteeing performance, safety, and reliability for shipbuilding and repair projects.
Easy Operation & Integration: The electric actuator allows for remote and automated control, easily integrating with central control systems (DCS/SCADA). It features options for on/off control or precise modulating control. A manual override handwheel is provided for emergency operation in case of power failure.
Versatile Configuration & Customization: We offer a wide range of sizes, pressure ratings, connection types, and actuator voltages to fit specific system requirements. Customizations like different seal materials, extended stems for insulation, fire-safe design, and specific paint coatings are available upon request.

Benefits for Your Operations:

Enhanced System Reliability: The robust construction and IP67 protection significantly reduce failure rates due to environmental factors, minimizing unplanned downtime and maintenance costs.
Improved Safety & Compliance: Meeting the CB/T3191 standard ensures the valve fulfills stringent marine safety regulations, protecting your assets, crew, and cargo.
Operational Efficiency: Electric actuation enables fast, remote valve operation, reducing manual labor and allowing for centralized monitoring and control of fluid systems.
Long-Term Cost Savings: The durable materials and design extend maintenance intervals and service life, providing a lower total cost of ownership over the valve's lifespan.

Frequently Asked Questions (FAQ):

Q: What does the CB/T3191 standard mean for this valve?
A: CB/T3191 is a Chinese national standard specifically for valves used on ships. Compliance ensures the valve meets defined requirements for design, materials, pressure testing, and performance suitable for marine applications, aligning with international maritime practices.
Q: Can this IP67 valve be used in permanently submerged applications?
A: The IP67 rating indicates protection against temporary immersion. For permanently submerged service, valves with a higher protection rating (like IP68) or specifically designed subsea valves would be recommended. Please inquire for such specific needs.
Q: Is the electric actuator reversible (for both opening and closing)?
A: Yes, the standard electric actuator is designed for bidirectional operation (quarter-turn). The rotation direction can typically be configured during installation or via internal wiring.
Q: What is the lead time for a custom order with non-standard size or material?
A: Lead times vary based on the complexity of customization. For standard sizes, it's typically 15-30 days. For special orders, our engineering team will provide a detailed timeline after reviewing your specifications.
Q: Do you provide accessories like limit switches or position transmitters?
A: Yes. Accessories such as mechanical or proximity limit switches, potentiometers for position feedback (4-20mA signal), and local position indicators are available as optional features.
Q: How do you ensure the quality of your valves?
A: Every valve undergoes a series of rigorous tests, including shell strength test, seat leakage test (air or water), and actuator function test. Our ISO9001 system governs the entire process from raw material inspection to final shipment.
Q: What are the main applications for this valve on a ship?
A: Common applications include ballast water systems, fuel oil transfer lines, cooling water circuits, bilge and drain lines, firefighting systems, and cargo handling systems.
Q: Can you supply documentation like material certificates and test reports?
A> Yes, we can provide relevant documentation, including material chemical and mechanical test certificates, pressure test reports, and certification of conformity, upon request.
