JIS F7364 Bronze Marine Gate Valve With Mill Test Report and Warranty
Product Spotlights
As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-quality fluid control solutions for demanding marine and industrial applications. Our JIS F7364 Bronze Marine Gate Valve is engineered to deliver reliable shut-off performance in corrosive seawater environments, backed by comprehensive documentation and a commitment to quality assurance. With an annual export value reflecting our global reach across continents from North America to Oceania, we understand the critical need for durable and specification-compliant components in marine projects.
This valve is designed to meet the stringent requirements of marine engineering, offering robust construction and long service life. Key features and benefits include:
- Corrosion-Resistant Bronze Body: Manufactured from high-grade bronze (CAC406 per JIS H5120), offering superior resistance to seawater corrosion, dezincification, and erosion, ensuring longevity in harsh marine conditions.
- JIS F7364 Standard Compliance: Specifically designed and tested to comply with the Japanese Industrial Standard for bronze gate valves used in ship piping systems, guaranteeing dimensional interchangeability and performance reliability.
- Reliable Sealing & Operation: Features a globe pattern design with a rising stem and outside screw & yoke (OS&Y) configuration. This allows for visual indication of valve position (open/closed) and keeps the threaded stem outside the flow path, preventing corrosion and ensuring smooth operation.
- Versatile Connection Options: Available with flanged or threaded ends to suit various piping system designs and facilitate easy installation and maintenance onboard vessels or offshore platforms.
- Documentation for Traceability: Each valve is supplied with a Mill Test Report (MTR), providing full traceability of material composition, mechanical properties, and confirming compliance with specified standards, which is crucial for quality audits and project documentation.
- Pressure Integrity: Built to withstand standard marine system pressures with ratings of 10K and 16K, ensuring safe and dependable operation in ballast, cooling, bilge, and general service lines.

Frequently Asked Questions (FAQ)
Q1: What is the significance of the JIS F7364 standard for this valve?
A: The JIS F7364 standard specifies the requirements for bronze gate valves used in ship piping systems. Compliance ensures the valve has the correct dimensions, materials, pressure ratings, and testing protocols required for marine applications, offering assurance of reliability and interchangeability.
Q2: Why is bronze (CAC406) used for marine valves?
A: Bronze CAC406 is a leaded tin bronze alloy known for excellent castability, good mechanical strength, and outstanding resistance to corrosion and erosion from seawater. It is a preferred material for marine valve bodies and components.
Q3: What is included in the Mill Test Report (MTR)?
A: The MTR is a certificate from the material mill. It typically includes the heat number, chemical composition analysis, mechanical property test results (tensile strength, yield strength, elongation), and confirms the material meets the specified standard (JIS H5120 CAC406). This provides full traceability.
Q4: Can this valve be used for freshwater applications?
A: Yes. While optimized for seawater corrosion resistance, its robust bronze construction makes it suitable for various fresh water, oil, and gas services in marine and industrial settings, provided pressure and temperature ratings are respected.
Q5: What are the available sizes and pressure classes?
A: Sizes and pressure classes are customizable based on project requirements. Common sizes range from 1/2" to 8", with pressure ratings of 10K and 16K being standard. Please contact us with your specific needs for a precise quotation.
Q6: Do you offer actuators for automated operation?
A: While the standard configuration is manual operation via handwheel, we can provide options for gear operators or discuss the feasibility of integrating electric, pneumatic, or hydraulic actuators based on your system's automation requirements.
Q7: What is the lead time for an order?
A: Lead time depends on order quantity, specification, and current production schedule. Standard specifications typically have shorter lead times. We prioritize clear communication and provide estimated delivery schedules upon order confirmation.
Q8: How does your warranty work?
A: We provide a standard warranty against defects in material and workmanship under normal use and service conditions as per our warranty policy. Specific terms and duration can be discussed and detailed in our commercial contract.
