As a professional manufacturer with a strong commitment to maritime fluid control solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our DN80 Marine Ball Valve with Hydraulic Operation. Engineered specifically for the demanding environments of seawater and fuel oil lines, this valve represents a synthesis of robust construction, reliable performance, and operational safety. With our ISO9001-certified production processes and years of experience serving global marine markets, we deliver a product designed to withstand corrosive media, high pressures, and the rigorous duty cycles of vessel operations. This valve is a critical component for ensuring secure and efficient flow control in ballast, cooling, fuel transfer, and other essential shipboard systems.
Core Product Features & Technical Advantages:
- Hydraulic Actuation for Remote & Precise Control: The integrated hydraulic actuator enables remote operation from a control room or central panel, eliminating the need for manual intervention in hard-to-reach or hazardous areas. This is crucial for emergency shutdown (ESD) sequences and automated process control.
- Superior Corrosion & Abrasion Resistance: Designed for seawater (high chloride content) and fuel oil service, critical wetted parts are available in materials like stainless steel (A351 CF8M/CF8) and chrome-plated balls. Seat materials such as PTFE or reinforced PTFE provide excellent chemical resistance and low friction.
- Robust Construction & High Pressure Integrity: The valve body, crafted from forged carbon steel (A216 WCB) or stainless steel, meets standards like API 6D and ASME B16.34. It is rated for pressures up to PN25/Class 300, ensuring leak-tight closure and long-term durability under pulsating loads.
- Fire-Safe Design Option: Available with fire-safe features per API 607/API 6FA standards, where the seat design provides a secondary metal-to-metal seal in case of a fire, preventing catastrophic fluid release.
- Bi-Directional Sealing & Low Torque Operation: The full-port or reduced-port design offers minimal pressure drop. The precision-machined ball and seat ensure reliable bi-directional sealing. The hydraulic actuator provides high torque output for smooth operation even after prolonged periods of inactivity.
- Easy Maintenance & Adaptability:"> Features a standard ISO 5211 mounting pad, allowing for easy interchangeability with other actuator brands or types. The modular design often permits in-line maintenance, reducing downtime and lifecycle costs.

Benefits for Your Marine Operations:
- Enhanced Safety & Compliance: Meets key marine standards, contributing to the overall safety system of the vessel and helping comply with classification society rules (e.g., ABS, DNV, LR, BV).
- Reduced Operational Risk & Downtime: Reliable remote operation minimizes personnel exposure to hazardous areas. Durable construction reduces failure rates and unscheduled maintenance.
- Improved System Efficiency: Full-port design minimizes pressure loss in critical lines, improving pump efficiency and reducing energy consumption for fuel transfer or ballast systems.
- Long Service Life & Lower TCO: The use of corrosion-resistant materials and robust design extends valve life in harsh seawater environments, lowering the total cost of ownership through reduced replacement frequency.
- Flexibility & Integration: Can be integrated with existing hydraulic power units (HPUs) and shipboard control systems. Customizable options for limit switches, positioners, and solenoid valves are available.
Frequently Asked Questions (FAQ):
-
Q: Is this DN80 valve suitable for both seawater and fuel oil applications?
A: Yes, it is specifically engineered for both media. Material selection (e.g., stainless steel body/ball, PTFE seats) provides the necessary corrosion resistance for seawater and compatibility with various fuel oils. -
Q: What hydraulic pressure is required to operate the actuator?
A: The standard hydraulic actuator is designed for a typical operating pressure range of 40 to 100 bar. The exact required pressure and flow depend on the required torque and operating speed, which we can specify based on your system parameters. -
Q: Are these valves certified by marine classification societies?
A> Shanghai Zhibang valves are manufactured under an ISO9001 quality system. Specific classification society approvals (like ABS, DNV-GL, LR) are available upon request and can be arranged for project-specific requirements, involving third-party inspection and testing. -
Q: What is the lead time for an order of these valves?
A: For standard configurations, lead times are competitive. Exact timelines depend on order quantity, material selection, and any customizations. We maintain efficient production planning to meet project schedules. -
Q: Can you supply the complete package including hydraulic power unit and controls?
A: While we specialize in the valve and actuator assembly, we can work with partners or provide guidance on system integration. We typically supply the valve with the mounted hydraulic actuator, ready for connection to your ship's hydraulic lines. -
Q: How does the fire-safe feature work on this ball valve?
A: In a fire-safe design, the primary soft seat (e.g., PTFE) seals under normal conditions. In a fire, this seat degrades, but a secondary metal seat (often integral to the ball or body) engages, providing a metal-to-metal seal to prevent or significantly reduce leakage. -
Q: What maintenance does this hydraulic ball valve require?
A> Maintenance is minimal. Periodic checks of the actuator for leaks, verification of smooth operation, and inspection of external seals are recommended. The valve itself, due to its simple design, often requires no routine internal maintenance under normal service. -
Q: Do you offer different flange standards?
A: Yes. While ANSI B16.5 is standard, we can manufacture valves with DIN, JIS, BS, or other flange standards to match your existing pipeline specifications. Please specify your requirement during inquiry.
