Highlight: Flanged welded ball valve
Product introduction:
A welded ball valve is a commonly used pipeline connector for controlling the flow of liquids or gases in pipelines. Compared
with other valves, the welded ball valve adopts a ball structure, featuring fast opening and closing, good throttling
performance, etc. The valve is mainly composed of a valve body, ball, sleeve, thrust ring, handle, etc., among which the ball
is the key component of the valve.

Product features:
1. High reliability: Welded ball valves adopt a ball structure, featuring quick opening and closing with reliable operation.
2. Excellent throttling performance: The ball of welded ball valves has a large through-bore diameter, resulting in low
pressure drop, large flow rate, and superior throttling performance.
3. High pressure and temperature resistance: Welded ball valves can withstand harsh working conditions such as high
pressure and high temperature, being widely used in industries like petroleum, chemical, and power.
4. Easy installation: Welded ball valves are connected to pipelines by welding, featuring simple installation and low risk of
leakage.
5. Good shut-off sealing performance: Welded ball valves adopt a ball structure, with the thrust ring pressing the ball to
form a reliable seal.
