Metallum Overseas is a trusted Top Entry Ball Valve Supplier in Mumbai, India, offering engineered ball valves for oil & gas, petrochemical, refining, natural gas, power generation, offshore and other demanding industrial applications. Top entry ball valves are designed with access to the internal components through the top of the valve body, allowing inspection and maintenance without removing the complete valve from the pipeline.
Our top entry ball valves can be configured according to valve size, pressure class, temperature, media, end connection and applicable project standards. The design can incorporate trunnion-mounted ball technology, soft or metal seats, double block and bleed capability, emergency sealant injection and other features according to application requirements.
A Top Entry Ball Valve is designed so that the bonnet or top closure can be removed to provide access to the ball, seats and other internal components. This arrangement is particularly useful for critical pipeline installations where maintenance and inspection are important.
Top entry construction can simplify internal inspection and repair while the valve remains installed in the pipeline. Depending on the design, these valves can be supplied with forged or cast bodies, trunnion-mounted balls and bidirectional sealing arrangements for demanding process and pipeline services.
Top entry trunnion mounted ball valves are suitable for high-pressure pipeline and process applications where stable ball support and dependable sealing are required. The trunnion arrangement supports the ball and helps reduce operating torque, particularly on larger valve sizes and higher pressure classes.
Metallum Overseas can supply top entry trunnion ball valves with soft or metal seats, self-relieving seat arrangements, double-piston seat designs and suitable sealing systems according to the operating conditions.
High pressure top entry ball valves are designed for demanding oil & gas, natural gas, petrochemical and industrial pipeline applications. They can be supplied in pressure classes up to ASME Class 2500, with valve configurations selected according to pressure, temperature, media and pipeline requirements.
Available options may include RF, RTJ and butt-welded end connections, manual or actuated operation, anti-static devices, anti-blowout stems, emergency sealant injection and low-emission stem sealing arrangements.
