Welded ball valves are known for their reliability and high performance in a variety of industries. One of their key advantages is their resistance to external leakage. Welded ball valves are highly adaptable to pressure and temperature changes, and they are designed not to leak within their marked pressure and temperature range. This makes them ideal for applications where tight shut-off is required.
The ball in a welded ball valve is processed with high accuracy, tracked by an advanced computer tester, ensuring that it operates smoothly and efficiently. This level of precision makes it a popular choice in industries such as petroleum, شیمیایی, natural gas, thermal, marine, قدرت الکتریکی, دارویی, متالورژی, food, military, ساخت و ساز, and engineering.

The difference between Welded ball valves and other ball valves
Welded ball valves differ from other ball valves in several ways. Firstly, the body of the valve is welded, rather than bolted or threaded, which makes it more durable and less prone to leaks.
Secondly, the ball itself is welded to the stem, which eliminates the possibility of the ball becoming dislodged during operation. Additionally, welded ball valves are designed with a reduced bore, which means that the opening in the ball is slightly smaller than the valve’s inlet and outlet ports. This results in a smaller flow path and higher fluid velocity, which can be advantageous in certain applications.
Finally, welded ball valves typically have a higher pressure rating than other types of ball valves, making them suitable for high-pressure applications in the oil and gas industry, as well as in chemical processing and other industrial applications.
