GB/T 584 Cast Steel Marine Globe Valve | For Steam & Oil
A heavy-duty cast steel valve designed for high-temperature and high-pressure systems. It handles steam up to 400°C, fresh water, and fuel oil. Available in straight and angle types with flange connections.
Accreditation and Certificates:
The GB/T 584 Marine Globe Valve is built for demanding environments. The main body is crafted from high-strength cast steel. This makes it withstand high nominal pressures ranging from 1.0 to 6.4 MPa. The internal components, such as the stem and disc, use stainless steel and carbon steel for durability.
This valve excels in systems transporting superheated steam, heavy fuel oil, and fresh water. The seal prevents leakage even under thermal stress. You can choose between Type A (Straight) and Type B (Angle) to fit your piping layout perfectly.

Key Features：
- High Temperature Resistance: Handles steam up to 400°C.
- Strong Body: Cast steel construction withstands high pressure.
- Tight Sealing: Low friction sealing surface prevents leaks.
- Versatile Design: Available in straight and angle configurations.
Applications：
- Steam Systems: Main boiler steam lines and auxiliary steam pipes.
- Fuel Systems: Transfer and supply lines for heavy oil and diesel.
- Water Systems: High-pressure fresh water circulation.
Installation & Maintenance：
Installation: Align the valve coaxially with the pipe. Tighten flange bolts evenly to avoid stress.
Maintenance: Clean surface debris regularly. Replace packing if leakage occurs at the stem.
Custom Options Available：
We provide customization services based on international standards such as ANSI, JIS, and DIN, ensuring compatibility with different global market requirements.
FAQ ：
Q1: Can this valve handle seawater?
A1: No. Cast steel is prone to corrosion in seawater. For seawater, please choose the GB/T 587 Bronze valve.
