Key Features & Technical Specifications
The JIS F7305 10K Marine Globe Valve DN80 incorporates robust construction and precision engineering to withstand harsh marine environments. Below are its core features and detailed parameters:
- Standard Compliance: Manufactured strictly according to JIS F7305 (Japanese Industrial Standard for marine valves), ensuring interchangeability and trusted performance.
- Pressure Rating: 10K (approximately 1.0 MPa / 145 psi) suitable for low-to-medium pressure shipboard systems.
- Size & Connection: DN80 (3-inch) flanged ends; flanges conform to JIS B2238 or equivalent, providing leak-proof joint.
- Trim Material: Bronze (copper alloy) for disc, seat ring, and stem – offers superior resistance to seawater corrosion and galling.
- Body Material: Standard cast iron (FC200 or similar), but available in ductile iron or bronze upon request.
- Operation: Handwheel-operated with rising stem; non-rising stem option available for limited-space installations.
- Temperature Range: Designed for operating temperatures from -10°C to 200°C (typical for water, oil, and steam).
- Testing: Each valve undergoes hydrostatic shell test (1.5x rated pressure) and seat leak test as per JIS B2003.

Frequently Asked Questions
Q1: What does “10K” mean in the product name?
A: 10K refers to the pressure rating under JIS standards, equivalent to 1.0 MPa (about 145 psi) at ambient temperature. It is suitable for low-pressure marine systems.
Q2: Is this valve suitable for steam service?
A: Yes, the bronze trim and cast iron body can handle saturated steam up to 200°C. For superheated steam, please consult our engineering team for material upgrades.
Q3: Can I get a valve with a bronze body instead of cast iron?
A: Yes, bronze body is available as a customization. Please specify when placing an order.
Q4: What is the delivery time for a standard DN80 valve?
A: For standard quantities (1–50 pcs), delivery is typically 15–25 days after confirmation. Larger orders may require 30–45 days.
Q5: Do you provide a test certificate?
A: Yes, we provide a hydrostatic test report and material certificate with each shipment. Third-party inspection is also accepted upon request.
Q6: How do I install this valve correctly?
A: Ensure flanges are clean and use proper gaskets (JIS compatible). Tighten bolts in a cross pattern to recommended torque. The valve should be installed with the stem vertical or horizontal, but not inverted.
Q7: Can this valve be used for fuel oil?
A: Yes, the bronze trim is compatible with heavy fuel oil (HFO). However, for HFO above 100°C, we recommend a stainless steel trim for better wear resistance.
Q8: What is the weight of the DN80 valve?
A: Approximate weight is 25 kg (55 lbs) for cast iron body. Bronze body version is slightly heavier.
