As a dedicated manufacturer with a strong export presence since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd specializes in producing reliable and compliant valves for demanding industrial applications. Our 5K Pressure Rating Gate Valve for Marine Piping, designed in accordance with JIS F7363, represents our commitment to providing robust solutions for shipbuilding, offshore platforms, and marine engineering. This valve is engineered to deliver secure isolation and control in critical fluid handling systems under moderate pressure conditions, ensuring operational safety and longevity.
This gate valve is a cornerstone for marine piping networks, offering dependable performance where reliability is paramount. Its design prioritizes durability, ease of operation, and strict adherence to recognized industry standards.
- JIS F7363 Compliance: Manufactured to meet the Japanese Industrial Standard for ship valves, ensuring compatibility and reliability in marine applications.
- 5K Pressure Rating: Suitable for systems operating at a pressure rating of 5 kgf/cm² (approximately 0.5 MPa), providing secure shut-off for various fluids.
- Robust Construction: Typically fabricated from high-grade carbon steel or stainless steel to withstand corrosive marine environments.
- Flanged Connection: Designed for easy integration into standard marine piping systems via flanged ends, facilitating installation and maintenance.
- Manual Operation: Features a handwheel for straightforward opening and closing, requiring no complex actuation systems.
- Full Bore Design: Allows for unobstructed flow when fully open, minimizing pressure drop across the valve.
- Versatile Sealing Options: Can be configured with metal-to-metal sealing for high-temperature applications or soft seals for tighter shut-off.
- Customizable Sizes: Available in a range of nominal sizes to match specific pipeline dimensions, with options available upon request.

Frequently Asked Questions (FAQ)
Q: What does "5K" pressure rating mean?
A: "K" stands for kgf/cm² (kilogram-force per square centimeter). A 5K rating means the valve is designed to withstand a pressure of 5 kgf/cm², which is approximately 0.5 MPa or 71 psi. It indicates the valve's pressure class for safe operation.
Q: Is JIS F7363 compliance important for my project outside of Japan?
A: Yes, it can be. JIS (Japanese Industrial Standards) are widely recognized and respected in the global marine industry. Using a JIS-compliant valve ensures it meets a specific set of quality and performance criteria, which can be beneficial for international shipbuilding and offshore projects, often simplifying approval processes.
Q: What materials are available for this valve?
A: The valve is typically offered in carbon steel for general applications and stainless steel (such as 304 or 316) for enhanced corrosion resistance in more aggressive marine environments. The specific material grade can be customized based on your fluid and operating conditions.
Q: Can this valve be operated automatically?
A: This product is designed as a manual gate valve operated by a handwheel. For automated operation, you would need to inquire about the possibility of adding an actuator assembly, which may be an optional or customizable feature.
Q: What are the typical sizes (DN) available?
A: Gate valves compliant with JIS F7363 are commonly produced in a range of nominal diameters. Specific available sizes from our production should be requested, as we can cater to common dimensions and potentially custom sizes.
Q: Is this valve suitable for steam service?
A: With its metal seat design and 5K rating, it can be suitable for low-pressure steam applications. However, the exact suitability depends on the material selection and temperature. It is crucial to confirm the operating parameters with our technical team for steam service.
Q: Does the valve come with any certifications?
A: Our manufacturing facility is ISO9001 certified, which governs our quality processes. The valve itself is manufactured to comply with the JIS F7363 standard. Specific product certifications (like third-party test reports) can be provided upon request.
Q: What is the lead time for orders?
A: Lead times vary based on order quantity, material choice, and specific size requirements. Given our established manufacturing capability and export experience, we strive to offer competitive lead times. Please contact us for an accurate estimate based on your needs.
