An all-welded ball valve is a type of ball valve with a fully welded body, providing exceptional strength, durability, and leak-proof performance. The welded design eliminates potential leak paths commonly associated with bolted or flanged connections, making it ideal for long-term, maintenance-free service.
Key Features:
1.Welded Body Construction:
The valve body is completely welded, with no bolts or gaskets, ensuring zero leakage from the body joints.
Highly resistant to environmental conditions, corrosion, and mechanical stress.
2. Sealing Mechanism:
Features a floating or trunnion-mounted ball design for effective sealing.
Seats made of PTFE, RPTFE, or metal-to-metal contact for handling different fluids and temperatures.
3.Material Options:
Typically made of carbon steel, stainless steel, or alloy steel.
Suitable for applications requiring corrosion or pressure resistance.
4.End Connections:
Butt-weld or socket-weld ends for seamless integration with pipelines.
Available with extended welding ends for buried or insulated pipelines.
5.Operation:
Manual (lever or gear-operated).
Automated with electric, pneumatic, or hydraulic actuators.
6.Pressure Ratings:
Designed to handle medium to high pressures, often compliant with standards like ANSI Class 150-2500.
7.Temperature Tolerance:
Can operate under extreme temperatures, depending on the material and seat selection.
Advantages:
Leak-Proof Design: Eliminates external leakage due to the absence of body joints.
Durability: Welded construction withstands high pressures and harsh environments.
Low Maintenance: Long service life with minimal maintenance requirements.
Compact and Lightweight: The absence of flanges reduces overall weight and space requirements.
Buried Applications: Ideal for underground or submerged installations due to its robust, sealed construction.
Common Applications:
Oil and Gas Pipelines: Widely used in long-distance transportation and distribution systems.
District Heating Systems: Suitable for hot water and steam pipelines.
Chemical and Petrochemical Industries: For handling corrosive and high-pressure fluids.
Offshore Platforms: Resilient against harsh marine environments.
Natural Gas Transmission: Leak-proof design ensures safety and efficiency in gas pipelines.
