The Top Entry Ball Valve is the perfect solution when you need a valve that offers easy maintenance, compact footprint, and rugged sealing—all without removing the valve from the pipeline. At Perfect Engineers, we manufacture top entry ball valves designed for high-pressure, high-temperature, and critical process applications across oil & gas, power, petrochemicals, and refining industries.
These valves are widely used where frequent inspection, repair, or welding accessibility is required on-site.
A Top Entry Ball Valve is a quarter-turn valve that allows access to the internal components—ball, seats, stem, seals—from the top side, without disturbing the connected piping. Unlike side-entry or split-body valves, this design allows inline maintenance, minimizing plant downtime.
Top entry valves are often cast or forged and are used in systems where safety, pressure integrity, and long-term reliability are non-negotiable.
