For Professionals Who Demand Safety, Stability & Performance In todays global industrial environment, safety and precision in flow control have never been more crucial. From upstream oil extraction to modern water treatment plants, engineers are seeking valve solutions that reduce operational risk, extend system lifespan, and simplify automation.The Fixed Ball Valve, also called the Trunnion-Mounted Ball Valve, has become a preferred choice in high-pressure systems—especially where tight shut-off and low torque actuation are non-negotiable.

For Professionals Who Demand Safety, Stability & Performance The Hard Seal Trunnion Ball Valve is engineered for high-pressure, large-diameter, and critical service applications. With a fixed-ball design supported by upper and lower bearings, it ensures relatively small operating torque, long-term sealing performance, and exceptional durability. Unlike soft-sealed valves, which may degrade over time or under harsh conditions, the hard seal mechanism ensures that the valve maintains its integrity.The metal-to-metal sealing surface is designed to withstand high pressures and temperatures, making it an ideal choice for industries such as oil and gas. Built to meet the rigorous demands of oil & gas, petrochemical, energy, marine, and water industries, it is the preferred choice for zero-leakage shut-off and reliable flow regulation.

For Professionals Who Demand Safety, Stability & Performance The Forged Steel Trunnion Ball Valve is a highly versatile and durable valve designed. The trunnion - mounted ball design ensures the ball is firmly supported at the top and bottom, preventing it from floating or shifting under high - pressure conditions. Forged steel is known for its protrude mechanical properties compared to cast steel. It has a more uniform grain structure, which results in higher tensile strength, better impact resistance, and improved resistance to deformation. This makes the Forged Steel Trunnion Ball Valve capable of withstanding extreme working conditions, such as high - pressure, high - temperature, and corrosive environments. It is widely used in industries such as oil and gas, chemical processing, water treatment, and power generation, where pressure and temperature variations are a common concern.

For Professionals Who Demand Safety, Stability & Performance The API 6D Trunnion Mounted Ball Valve is engineered to meet the demanding requirements of pipeline and industrial applications. Designed in accordance with API 6D standards, this valve delivers consistent performance, long-term durability, and enhanced safety in both onshore and offshore operations. It is ideal for oil and gas, petrochemical, power generation, and other process industries requiring dependable shutoff and flow regulation. Unlike floating ball valves, it employs a fixed ball supported by trunnion bearings, reducing seat load and keep it as small as possible operational torque. This design ensures long-term reliability, effective sealing, and operational safety in both upstream and downstream pipeline systems.
