As a professional manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance marine valves for critical applications. Our Marine Gate Valve for Engine Room Cooling Water Lines, manufactured in strict compliance with JIS F7363 5K standard, is engineered to deliver reliable shut-off and flow control in the demanding environment of ship engine rooms. With an annual export value reflecting our global reach across markets from North America to Southeast Asia, we understand the precise requirements for marine cooling systems. This valve is designed to ensure uninterrupted cooling water supply, which is vital for maintaining optimal engine temperature and preventing costly downtime at sea.
The core value of this valve lies in its robust construction and adherence to recognized Japanese Industrial Standards (JIS), providing shipbuilders and marine engineers with a component they can trust for essential cooling circuits. Operating from our strategic location in Shanghai, with major ports of shipment including Shanghai, Guangzhou, and Hong Kong, we ensure efficient logistics for our international clientele.
Detailed Product Features & Technical Advantages:
- JIS F7363 5K Compliance: Manufactured precisely to the Japanese Industrial Standard F7363 for 5K pressure rating, ensuring compatibility with a wide range of marine piping systems and international acceptance.
- Optimized for Cooling Water: Specifically designed for engine room cooling water service, resistant to corrosion from both fresh and treated sea water, prolonging service life.
- Robust Sealing Mechanism: Features a parallel wedge or solid wedge design (depending on model) with bronze or stainless steel seats, providing a bubble-tight seal essential for controlling cooling water flow.
- Durable Construction: The valve body is typically crafted from high-grade cast iron or ductile iron, offering excellent strength and corrosion resistance for long-term marine operation.
- Easy Operation & Maintenance: Equipped with a handwheel-operated rising stem. The open/close position is visually clear, and the design allows for easier maintenance and packing replacement if needed.
- Flanged Connection: Comes with JIS standard flanged ends, facilitating secure and leak-free installation into existing cooling water pipelines.

Frequently Asked Questions (FAQ):
Q1: What does the "5K" rating in JIS F7363 5K mean?
A1: In the JIS standard, "K" stands for "Kogu" (pressure) rating. 5K corresponds to a pressure rating of approximately 10 bar (PN10) at ambient temperature. It indicates the valve's maximum allowable working pressure for the specified service.
Q2: Is this valve suitable for raw (untreated) sea water service?
A2: While designed for cooling water, which often uses treated sea water or fresh water, its standard materials (cast iron/bronze) offer good corrosion resistance. For highly aggressive raw sea water, specific material upgrades like higher-grade stainless steel seats may be recommended. Please consult with our engineers for your specific medium conditions.
Q3: Are the flanges compatible with ANSI or DIN piping systems?
A3: JIS flanges have their own dimensional standards. Direct bolt-to-bolt compatibility with ANSI or DIN flanges is not guaranteed without adapters. It is crucial to specify JIS F7363 flanges if your existing piping is to the same standard, or discuss adapter solutions if connecting to different flange standards.
Q4: What is the typical lead time for an order of these valves?
A4: Lead time depends on order quantity and specific material requirements. As a manufacturer based in Shanghai with efficient supply chains, we can often provide competitive lead times. Stock status and precise timelines can be confirmed upon receipt of your inquiry.
Q5: Can you provide different stem types, like non-rising stem (NRS)?
A5: The standard offering is a rising stem design, which provides clear visual indication of the valve position. Non-rising stem configurations may be available as a customization option. Please inquire with your specific requirements.
Q6: Do you offer actuators for remote operation of this valve?
A6: The standard valve is manual handwheel operated. However, as a manufacturer, we can typically facilitate the mounting of electric, pneumatic, or hydraulic actuators based on customer specifications. This would be a customized solution.
Q7: What testing is performed on these valves before shipment?
A7: In line with our ISO9001 system and common industry practice, each valve typically undergoes shell strength tests and seat leakage tests (usually with water or air) to verify its pressure integrity and sealing performance before it leaves our factory.
Q8: What are the main ports you ship from, and what are the typical Incoterms offered?
A8: We primarily ship from Shanghai, Guangzhou, Hong Kong, and Beijing ports. We are experienced in handling exports under common Incoterms like FOB, CIF, or CFR, depending on the destination within our extensive main markets from the Americas to Europe, Asia, Africa, and Oceania.
