Elite Flow Control’s Top Entry Ball Valves are premium, large-bore trunnion mounted ball valves engineered for in-line maintenance and inspection without removing the valve from the pipeline – a defining advantage in buried, insulated, or difficult-to-access piping systems. Available in sizes from 2″ to 36″ (DN50 to DN900) across pressure classes CL150 to CL2500, these valves are the trusted specification for demanding pipeline and process applications in oil & gas, petrochemical, power generation, and offshore industries.
The top entry design allows the bonnet, ball, seats, stem, and all internal components to be accessed, inspected, and replaced directly from above the valve body without breaking the pipeline connection. This dramatically reduces maintenance downtime, eliminates the need for pipe cutting or valve removal, and significantly lowers the total cost of ownership over the valve’s service life – making it the preferred choice for critical, large-bore pipeline systems where availability is paramount.
The trunnion mounted ball configuration ensures the ball is held firmly in position regardless of line pressure, transmitting pipeline loads directly to the body and dramatically reducing seat wear and operating torque compared to floating ball designs. Sealant injection to both the stem and seat areas provides an additional in-service sealing capability, ensuring the valve can be restored to full integrity without shutdown in the event of minor seat wear or damage.
Available with metal seat or primary metal seat with secondary soft insert for high-temperature, wear-resistant, and abrasive service conditions, and with an extended bonnet option for cryogenic or high-temperature applications. Full automation compatibility – including pneumatic, electric and hydraulic actuators – as well as emergency shut down capability and locking/interlocking facilities make these valves fully qualified for safety-critical service.
Constructed from a comprehensive range of ASTM-standard materials across carbon steel, alloy steel, stainless steel, and duplex stainless steel, with a wide selection of seat, seal, and packing materials to match virtually any process fluid or service condition.
