What is Top-Entry Ball Valve?
Top-entry ball valves are a type of valve used to open or close a liquid or gas line. The advantage of top-entry ball valves is that they offer full bore access through the top of the valve body, making them easy to install or repair without removing the entire valve from its piping system. This also means that they require less maintenance than traditional valves, which need to be removed from their lines to be serviced.
How Do Top-Entry Ball Valve Work?
The valve body houses an internal disc attached to the stem, which extends up through the top entry port. When you turn the handle on the stem clockwise, it moves down into a closed position, while turning it counter clockwise moves it up into an open position, allowing fluid/gas to flow through it.
Top-Entry Ball Valve Uses
The main purpose of top-entry ball valves is to regulate flow into and out of a pipe or pipeline system. This can be done by controlling the opening or closing of the valve’s internal disc, which is connected to a stem that extends out through the top entry port on the valve body. The handle on the stem is then used to turn off or on the flow as desired.
