Design Features
Our top-entry trunnion ball valves are designed to adhere to international standards such as API 6A, API 6D, ASME B16.34, ISO 17292, and others upon request. These high-performance valves are specifically engineered for ease of maintenance, allowing for in-line repair or replacement of internal components without the need for dismantling the valve from the pipeline. The trunnion supported design and unique seat retraction technique provide unmatched convenience and efficiency.
The series Top Entry Trunnion Ball Valve is suitable for double block and bleed application because each ball seat independently shuts off the line fluid on the upstream side. In case of accidental seat or stem leakage, an emergency stop can be achieved through the secondary sealant injection system for the stem and seat. This system ensures that the valve maintains its integrity and prevents any potential risks or hazards. Safety measures, such as the ability to shut off the line fluid individually, make this valve highly reliable and a valuable addition to any industrial application.
Our range includes a variety of seats, including soft, metal, and composite options. These seats offer the flexibility to be configured with either a single or double piston effect. This configuration allows for an efficient double block and bleed (DB&B) system that can be applied in both closed and open positions, upon request.

No trim in steam flow.
To reduce the occurrence of flow induced vibration, a profile that gradually tapers is employed. This ensures that the flow smoothly enters and exits the system, without causing any turbulence or instability. By minimizing the potential for vibration, the overall performance and durability of the system can be improved.
