Marine-Grade Bronze Globe Hose Valve – In-Depth Technical Specifications (Compliant with JIS F7334 Standard)
Product Overview
The JIS F7400 Marine-Grade Bronze Globe Hose Valve is specifically engineered to facilitate seamless marine hose connections. It comes in two distinct pressure classes, namely 5K (equivalent to PN10) and 10K (equivalent to PN20), and offers a range of sizes spanning from DN40 up to DN65, catering to diverse marine piping requirements.
Key Features
Material Versatility
- Standard Material: The valve is primarily constructed using high-quality bronze (BC6), which is well-known for its excellent corrosion resistance and durability in marine environments.
- Optional Materials: For enhanced performance or specific application needs, customers have the option to choose from stainless steel (SUS316), known for its superior strength and resistance to a wide range of chemicals, and gunmetal (LG2), which offers a good balance of mechanical properties and corrosion resistance.
Pressure Capabilities
- 5K Pressure Class: This valve can withstand a working pressure of 0.5 MPa, making it suitable for moderate-pressure marine applications.
- 10K Pressure Class: For more demanding scenarios, the 10K version can handle a working pressure of 1.0 MPa, ensuring reliable operation under higher pressure conditions.
Connection Options
- Flanged Connections: The valve is available with flanged connections conforming to JIS B2210/B2240 standards. These flanged connections provide a secure and leak-proof joint, facilitating easy installation and maintenance in marine piping systems.
- Threaded Connections: Additionally, threaded connections in BSPT/NPT standards are also offered. This provides flexibility in connecting the valve to various types of marine hoses and fittings, depending on the specific requirements of the application.
Comprehensive Pressure Testing Parameters
| Nominal Pressure (MPa) | Seal Pressure Test (MPa) | Intensity Pressure Test (MPa) | Water Pressure Test (MPa) |
|---|---|---|---|
| 0.49 (for 5K class) | 0.75 | 1.03 | 0.69 |
| 0.98 (for 10K class) | 1.5 | 2.06 | 1.37 |
| These rigorous pressure tests ensure that the valve can withstand the specified pressures without any leakage or failure, providing peace of mind in critical marine operations. |
Detailed Component Parameters
| Part Name | Material |
|---|---|
| Body, Bonnet | Tin-bronze (ZQSn10-21), which offers excellent corrosion resistance and mechanical strength, ensuring long-term reliability in marine settings. |
| Disc, Seat | Albronze (QAL9-21), known for its wear resistance and ability to maintain a tight seal, even under high-pressure conditions. |
| Packing | PTFE (SFT-2), which provides a reliable and low-friction seal, preventing leakage and ensuring smooth operation of the valve. |
