Top entry ball valve is only with single integral Body and has the same features as side entry ball valve , such as Emergency Sealant Injection, Low Emission Packing, Fire Safe, Anti-Static and Anti-Blowout Stem,The characteristic of the top entry ball valve is that the ball is fixed at the top of the valve body, and it is controlled to open and close by the valve stem. This design enables the ball valve to perform excellently under conditions of high pressure, high temperature, and high flow. Top entry ball valves are widely used in industries such as chemical, petroleum, natural gas, and pharmaceuticals, particularly suitable for pipeline systems that require frequent switching.
