As a specialized manufacturer with a proven track record since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to introduce our high-performance Electric Marine Gate Valve designed specifically for demanding seawater cooling applications. Engineered to meet the rigorous JIS F7363 standard, this valve series combines reliable shut-off capability with the convenience and precision of electric actuation, making it an essential component for modern marine and offshore systems. Our commitment to quality, underscored by our ISO9001 certification, ensures that every valve delivers durability and consistent performance in corrosive seawater environments, helping vessel operators and shipyards enhance system reliability and reduce maintenance downtime.

This valve is engineered to provide secure isolation in seawater cooling loops, bilge systems, ballast water management, and other critical marine piping networks. Its robust construction and electric operation offer significant advantages over manual valves in terms of operational efficiency, safety, and integration with automated control systems.

Key Product Features & Technical Advantages:

Corrosion-Resistant Construction: Manufactured from premium grades of bronze or 316 stainless steel, offering exceptional resistance to seawater, chlorides, and marine atmospheres, ensuring a long service life.
JIS F7363 Compliance: Designed and tested to meet the Japanese Industrial Standard for marine valves, guaranteeing dimensional interchangeability, material suitability, and performance reliability recognized in global shipbuilding.
Electric Actuator Integration: Features a reliable electric motor actuator for remote open/close control. This allows for integration into centralized control panels, SCADA systems, or automated sequences, eliminating the need for manual handling in hard-to-reach areas.
Bubble-Tight Shut-Off: Precision-machined wedge and seat design ensures a bubble-tight seal when closed, preventing leakage and ensuring efficient system operation.
Low Torque Operation: The optimized design reduces operating torque, which prolongs actuator life and reduces power consumption.
Versatile Mounting: The compact actuator design and flanged connection (JIS 10K/16K standard) facilitate easy installation into existing or new piping systems.

Frequently Asked Questions (FAQ):

Q: What is the primary advantage of an electric actuator over a manual handwheel for this gate valve?
A: The electric actuator allows for remote operation and automation. It can be controlled from a central bridge or engine control room, integrated into automated sequences (like cooling system start-up/shutdown), and eliminates the need for crew to access potentially hazardous or inconvenient valve locations manually, enhancing both safety and operational efficiency.
Q: Why is compliance with the JIS F7363 standard important for marine valves?
A: JIS F7363 is a widely recognized Japanese Industrial Standard specifically for marine valves. Compliance ensures the valve's dimensions, materials, pressure ratings, and testing methods are suitable for marine service. It guarantees interchangeability with other JIS-standard components and is often specified or required by shipbuilders, particularly in Asia, facilitating smoother procurement and installation.
Q: Can this valve be used with fluids other than seawater?
A: Yes, while optimized for seawater cooling, the corrosion-resistant materials (bronze, stainless steel) make it suitable for other corrosive media such as brackish water, certain chemicals, and oily water systems found on ships and offshore platforms. Please consult with our engineers for specific fluid compatibility.
Q: What are the available power supply options for the electric actuator?
A: Our actuators are customizable to match your vessel's electrical system. Standard options include AC 110V, 220V, 380V at 50/60Hz, and DC 24V. We can configure the actuator to meet your specific voltage and frequency requirements.
Q: How is the valve protected against the harsh marine environment?
A: The valve body uses seawater-resistant materials. The electric actuator housing typically comes with a high Ingress Protection rating, such as IP66 (dust-tight and protected against powerful water jets) or IP67 (protected against temporary immersion). This protects the internal electrical components from salt spray, humidity, and washdowns.
Q: What is the delivery lead time for an order of DN150 valves?
A: As a manufacturer with streamlined production, we maintain stock for common sizes and specifications. For standard DN150 valves, lead time is typically short. For large or customized orders, we provide an accurate timeline upon receipt of your detailed requirements. Our multiple shipping ports enable flexible and efficient logistics.
Q: Do you offer valves with different seat types for better sealing?
A: Yes. We offer both traditional metal-to-metal seats (often with Stellite hardening for wear resistance) and resilient seats (using EPDM or NBR). Resilient seats generally provide a tighter seal at lower pressures and can accommodate minor solids in the fluid, while metal seats are suitable for higher temperatures and more abrasive conditions.
Q: Can you provide support for valve sizing and selection for our specific cooling system?
A: Absolutely. Our technical team can assist you in selecting the correct valve size (DN80-DN200), pressure class, material, and actuator specification based on your system's flow rate, pressure, fluid characteristics, and control requirements. We provide detailed CAD drawings and documentation to aid in your design process.
