American Standard Cast Steel Trunnion Ball Valve: Performance Analysis and Application Review

The US Standard Cast Steel Trunnion Mounted Ball Valve is an important industrial valve designed in accordance with US national standards, mainly used to cut off or regulate fluid flow in pipelines.

Advantages:

1. Good sealing performance: As the sealing surface of the ball valve is a sphere, and in the closed state, the medium pressure makes the sphere tightly contact the valve seat, thereby achieving a good sealing effect.

2. Lightweight switch: The ball valve only needs to rotate 90 degrees for easy operation and fast switching speed.

3. Strong flow capacity: The channel of the ball valve is straight, with low fluid resistance and high flow capacity.

4. Wide application range: suitable for various temperature and pressure media, such as water, oil, gas, etc.

Disadvantages:

1. Difficulty in maintenance: Due to the complex structure of ball valves, once problems arise, maintenance can be quite difficult.

2. Poor wear resistance: For media containing solid particles, the wear resistance of ball valves is poor.

Usage:

American standard cast steel fixed ball valves are widely used in pipeline systems in industries such as petroleum, chemical, and natural gas, to control the flow of media.

Material specifications and types:

1. Material: Cast steel material enhances the pressure resistance and wear resistance of the valve, enabling it to adapt to more complex working environments.

2. Specifications: The external connection size and weight of the fixed ball valve may vary depending on the working pressure and diameter. For example, for PN16MPa and DN50 ball valves, their external dimensions are 216mm and their weight is 50kg.

Overall, the American standard cast steel fixed ball valve is a valve with superior performance and wide application, but it is also necessary to pay attention to its maintenance and upkeep during use to ensure its normal operation.
