JIS F7306 Bronze Angle Globe Valve for Seawater Cooling System Marine Engine Room
Product Spotlights
Shanghai Zhibang Valve Manufacture Co., Ltd, established in 2016 with an annual export value of US$1-1.5 million, proudly presents the JIS F7306 bronze angle globe valve – a specialized solution for seawater cooling systems in marine engine rooms. Crafted from high-grade bronze, this valve offers exceptional corrosion resistance against saltwater, ensuring reliable performance in demanding marine environments. Its angle body design minimizes flow resistance and pressure drop, making it an ideal choice for space-constrained piping layouts typical of engine rooms. With ISO9001 certification backing our production quality, you can trust every valve meets rigorous standards.
Key Features & Technical Specifications:
- Material Excellence: Made from corrosion-resistant bronze (CuSn5Zn5Pb5 or equivalent), ideal for seawater and brackish water applications.
- JIS F7306 Compliance: Manufactured strictly according to Japanese Industrial Standards for marine valves, ensuring interchangeability and reliability.
- Angle Globe Design: 90-degree turn between inlet and outlet reduces turbulence; suitable for horizontal or vertical installation.
- Precision Machining: Stem and disc sealing surfaces are finely ground to provide bubble-tight shut-off even under low pressure.
- Easy Maintenance: Renewable disc and seat ring allow quick on-site replacement without removing the valve from the pipeline.
- Multiple End Connections: Available in flanged (JIS 10K/16K) or threaded (BSP/NPT) options to fit existing systems.
- Wide Size Range: From 15mm (1/2") to 300mm (12") – custom sizes available upon request.

Frequently Asked Questions
-
Q: Is this valve suitable for freshwater or only seawater?
A: While primarily designed for seawater, the bronze material also works well in freshwater, treated water, and oil-free applications. For specific media compatibility, please consult our technical team. -
Q: Can I get a valve with a flanged connection conforming to JIS 10K?
A: Yes, flanged ends are available in JIS 10K, 16K, or other standards upon request. Please specify your requirement when ordering. -
Q: What is the lead time for standard sizes?
A: For common sizes (1/2" to 4"), our typical lead time is 15-25 days after order confirmation. Larger sizes may require 30-45 days. -
Q: Does the valve come with a certificate of material test?
A: Yes, we provide material test certificates (MTC) for every bronze melting batch. Pressure test reports are also included. -
Q: Can this valve be used for steam service?
A: Although primarily for liquid, it can handle low-pressure steam up to 1.0 MPa. For high-temperature steam, we recommend our stainless steel series. -
Q: Is the handwheel removable for actuator mounting?
A: Yes, the top flange is designed to accept standard ISO5211 mounting pads for pneumatic or electric actuators. Please inform us in advance. -
Q: What packing material is used for the stem seal?
A: Standard packing is PTFE-impregnated graphite, providing low friction and reliable sealing. Alternative materials like pure graphite or flexible graphite are optional. -
Q: Do you offer sample valves for testing?
A: Absolutely – we can provide sample valves with competitive pricing. Sample freight and payment terms can be discussed.
