Top Entry Ball Valve
When selecting ball valves, utilization of a top entry design, will permit easy access to internal components for service and parts replacement, without having to remove the ball valve from the line. The ability to make quick repairs is especially important at start-up time when valve damage from fabrication debris is most likely to cause expensive down time and project delays.
