As a leading manufacturer with ISO9001 certified production systems, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-reliability fluid control solutions for demanding marine applications. Our JIS F7300 Standard Electric Marine Ball Valve with Manual Override Function is engineered to deliver precise and dependable flow control in the challenging saltwater environment, ensuring operational safety and system integrity for vessels worldwide. With nearly a decade of experience since our establishment in 2016, we understand the critical need for valves that combine automated efficiency with fail-safe manual operation, a core value proposition of this product designed for global maritime fleets.

This valve is a cornerstone for modern marine piping systems, offering seamless integration and robust performance. Its design and construction prioritize longevity and minimal maintenance, even under constant exposure to corrosive elements.

Key Features & Technical Advantages:

Dual-Mode Operation: The integrated electric actuator allows for remote and automated control, while the manual override function ensures the valve can be operated locally during power loss or maintenance, providing an essential safety feature.
JIS F7300 Compliance: Manufactured strictly in accordance with Japanese Industrial Standards for shipbuilding, ensuring dimensional interchangeability, material suitability, and performance reliability recognized in international marine projects.
Corrosion-Resistant Construction: Available in body materials like cast steel with specialized coatings or stainless steel (304/316), providing excellent resistance to seawater, humidity, and marine atmospheres.
Bubble-Tight Sealing: Utilizes advanced seat materials such as PTFE or reinforced PTFE, ensuring zero leakage and long service life even after frequent cycling.
Versatile Power Options: The electric actuator supports a wide range of power supplies (e.g., 24VDC, 110VAC, 220VAC, 380VAC), making it adaptable to different shipboard electrical systems.
Compact & Robust Design: Engineered for space-saving installation in engine rooms, ballast systems, fuel lines, and cooling water circuits without compromising on strength.

Frequently Asked Questions (FAQ):

Q: What is the primary advantage of the manual override function on an electric valve?
A: The manual override allows operators to open or close the valve manually using a handwheel or crank in case of a power failure, actuator malfunction, or during maintenance. This ensures the fluid system remains controllable under all circumstances, which is a vital safety requirement in marine applications.
Q: Why is compliance with JIS F7300 important for marine valves?
A: JIS F7300 is a widely recognized Japanese Industrial Standard specifically for shipbuilding valves. Compliance guarantees that the valve's dimensions, materials, pressure ratings, and testing methods meet rigorous international criteria for marine service, ensuring compatibility and reliability in global fleets.
Q: Can this valve be used with fluids other than seawater?
A: Yes. While designed for marine corrosive environments, the valve's material options (like stainless steel or special coatings) make it suitable for a variety of media onboard, including fuel oil, lubricating oil, compressed air, and fresh water. The seat material can be selected based on the fluid's chemical compatibility.
Q: What are the available power supply options for the electric actuator?
A: We offer actuators compatible with common marine electrical systems, including 24VDC, 110VAC, 220VAC, and 380VAC. The specific voltage, phase, and frequency can be customized to match your vessel's power grid upon request.
Q: How is the corrosion protection for the valve body ensured?
A> Corrosion protection is achieved through material selection (e.g., stainless steel) and surface treatments. For carbon steel bodies, we typically apply epoxy coatings or galvanization suitable for saltwater exposure. The exact protection method can be specified based on the service environment.
Q: Is the valve suitable for both above-deck and below-deck installations?
A: Yes. With a standard IP67 rating, the actuator is protected against dust ingress and temporary immersion, making it suitable for engine rooms and other below-deck spaces. For more exposed locations, higher IP ratings (like IP68) are available as an option.
Q: Do you provide valves with different end connections besides flanged?
A: While flanged ends per JIS standards are the most common for marine piping, we can also provide valves with screwed (threaded) ends or weld ends upon request to fit specific system designs.
Q: What is your lead time for standard and customized orders?
A> Standard sizes and specifications typically have shorter lead times. For customized orders involving special materials, actuators, or certifications, the lead time will be communicated clearly during the quotation process. Our efficient manufacturing and multiple shipment ports help ensure timely delivery.
