Cast fully welded ball valve is an industrial ball valve manufactured by casting process with fully welded body design. This means the valve body is made from a single piece of cast material (usually carbon steel or stainless steel), which increases its strength and durability.
What are the main features of cast fully welded ball valves?
1. Welded valve body
The valve body is formed by welding two or more halves or sections together, forming a seamless and leak-proof construction.
This welded body design increases strength, eliminates potential leak points, and withstands high pressure and high temperature applications.
2. Ball and seat
The ball is usually made of metal such as stainless steel and is precision machined to ensure a tight seal when it is near the seat.
The valve seat is usually made of materials such as PTFE (polytetrafluoroethylene) or reinforced PTFE, which has excellent sealing performance and chemical resistance.
3. Full bore
Cast fully welded ball valves are usually designed with a full bore.
This means that the inside diameter of the valve matches the inside diameter of the pipe, allowing for minimum pressure drop and maximum flow.
What are the advantages of cast fully welded ball valves?
1. Reliable sealing
The combination of precision machined ball and seat and resilient seat material provides reliable sealing performance and minimizes the risk of leakage.
2. Maintenance-free
Cast all-welded ball valves are designed for long-term reliability and are generally considered maintenance-free due to their robust construction and welded body design, requiring no periodic adjustments or replacements.
3. Suitable application
These valves are commonly used in various industries including oil and gas, petrochemical, power generation, pipeline and other applications encountering high pressure, high temperature and corrosive environments.
Summarize
Cast fully welded ball valves provide a robust and reliable solution for fluid control in demanding applications. Its welded body design, positive seal and maintenance-free nature make it suitable for critical processes requiring excellent durability and leak-free performance.
