Shanghai Zhibang Valve Manufacture Co., Ltd. has been a trusted manufacturer of industrial valves since 2016. Our Cast Iron JIS F7306 Angle Stop Valve is specifically engineered for marine piping systems, offering reliable flow control under demanding conditions. With an annual export value of US$1-1.5 million and an ISO9001 certified quality management system, we deliver products that meet rigorous international standards. This angle stop valve combines durable cast iron construction, precise JIS F7306 dimensional compliance, and flexible pressure ratings of 5K or 10K to ensure dependable performance in shipboard applications.
The flanged connection design simplifies installation and maintenance, while the angle body configuration minimizes pressure drop and reduces turbulence. Available in sizes from DN15 to DN100, this valve is suitable for a wide range of marine piping systems, including seawater cooling, ballast, fuel oil, and fire-fighting lines. Below, we detail the key features, technical specifications, and benefits that make this valve an excellent choice for your marine projects.
Key Features & Benefits
- Robust Cast Iron Body: High-strength cast iron resists corrosion and mechanical stress, ensuring long service life in marine environments.
- JIS F7306 Compliance: Manufactured to Japanese Industrial Standard F7306, guaranteeing interchangeability and reliable flange dimensions.
- Dual Pressure Ratings (5K / 10K): Choose the appropriate rating for your system pressure requirements; both options are available upon request.
- Flanged Connection: Flat-face flanges with standard bolt holes for easy, leak-tight installation – compatible with JIS B2220 flanges.
- Angle Body Design: 90-degree turn reduces pipe stress and provides smooth flow direction change, lowering erosion and noise.
- Wide Size Range: DN15 (1/2") to DN100 (4") covers most marine branch lines and main pipelines.
- Versatile Application: Suitable for fresh water, seawater, oil, and non-corrosive gases with operating temperatures up to 120°C (depending on material).
- Easy Maintenance: Bonnet assembly allows quick access to internal components without removing the valve from the pipeline.

Frequently Asked Questions
-
Q: What is the difference between 5K and 10K pressure ratings?
A: 5K refers to a nominal pressure of 5 bar (approx. 73 psi) while 10K is 10 bar (approx. 145 psi). The 10K valve has thicker walls and higher strength. We can supply either rating based on your system pressure. -
Q: Can this valve be used with seawater?
A: Yes, the cast iron body provides good corrosion resistance. For extremely corrosive environments, we can apply anti-corrosion coatings or offer optional bronze trim. -
Q: Are the flanges compatible with JIS B2220?
A: Yes, the flanges are designed to match JIS B2220 flat-face dimensions and bolt hole patterns for size DN15 to DN100. -
Q: Do you provide actuator mounting options?
A: Yes, the top flange can be machined to accept pneumatic, electric, or hydraulic actuators. Please specify your requirements when ordering. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 10 pieces per size, but we can accommodate smaller orders for sample or trial purposes. Contact our sales team for details. -
Q: How do you ensure quality?
A: We conduct 100% hydrostatic and shell tests on every valve. Our factory is ISO9001 certified, and we can provide material certificates and test reports upon request. -
Q: What is the typical lead time?
A: For standard sizes (DN15-DN50) in 5K rating, lead time is 15-20 working days. Larger sizes and custom configurations require 25-30 working days. -
Q: Can you provide special coatings for offshore use?
A: Yes, we offer epoxy paint, nylon coating, or hot-dip galvanizing as optional surface treatments. Kindly advise the required specification.
